SHOCKING..Could We Possibly Be Mistaken! How to convert amps to watts (W) How to convert electric current in amps (A) to electric power in watts (W). You can calculate watts from amps and volts. You can't convert amps to watts since watts and amps units do not measure the same quantity. DC amps to watts calculation formula The power P in watts (W) is equal to the current I in amps (A), times the voltage V in volts (V): Van der Waerden numbers. Van der Waerden's theorem is a theorem in the branch of mathematics called Ramsey theory. It relates to ways that collections can be coloured, in order, avoiding spacing of colours that are a defined length arithmetic progression apart. They are named after the Dutch mathematician B. L. van der Waerden. How to calculate cubic feet. Article Category: Units | 0 Comments It's not an everyday problem, but there will be times when you need to calculate the capacity of something. Instead of staring blankly into the trunk of your car, getting a tension headache trying to find the biggest bathtub, or weeping when confronted by the decision over buying a new fridge-freezer or oven, just take control! How to do it There are only three measurements you need to take to work out the volume or capacity in cubic feet: length, width and height. Once you've obtained those measurements, it’s only a case of multiplying them together. Length (feet) x Width (feet) x Height (feet) = Volume in cubic feet (written as Xft3) If the shape is irregular, mentally divide it into regular shapes and calculate the volume for each part separately, before adding them all together. Maths and English Practice. Recreational Mathematics. Hare and Hounds Puzzle. Hare and Hounds On each turn, a single hound moves to a directly connected empty square, followed by the hare's similar move. The hounds may only move vertically or forward (to the right), not backward. The hare may move in any direction. There are no captures. The hounds win by trapping the hare so that he is unable to move. Hexagon Geometry Puzzle. A quick little geometery puzzle this week, shown to me by a friend. It's not too challenging. If the regular hexagon above is one square unit, what is the area of the yellow quadrilateral? Names of Geometric Shapes—With Pictures. Most children know the names of basic two-dimensional shapes before they enter school. Squares, triangles, circles, and ovals are easy for young children to recognize and draw, even if their other math skills are still developing. As they get older, they can discern more differences among shapes and start to learn more precise words for the wide variety of geometric objects they encounter in life. Soon, they begin to learn names of three-dimensional figures like cubes, cones, cylinders, spheres, and more.

The following list of shapes covers both common and more rare geometrical figures. To make learning their names easier, each shape name is accompanied by a picture. All the drawings of two-dimensional shapes and polyhedra in this article (except the octahedron, icosahedron, dodecahedron, and rhombic dodecahedron) were created by the author. This is a well-made wooden sorting box with sliding top and 12 wooden shape blocks painted in durable, bright colors. Space group. The space group of hexagonal H2O ice is P63/mmc. The first m indicates the mirror plane perpendicular to the c-axis (a), the second m indicates the mirror planes parallel to the c-axis (b) and the c indicates the glide planes (b) and (c). The black boxes outline the unit cell. Three-Dimensional Shapes. This page examines the properties of three-dimensional or ‘solid’ shapes. Math.
