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. For example, an L shaped cabinet designed to fit the corner of a room could be dealt with as two different rectangles, one longer, one shorter. Real world examples. Maths and English Practice. 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. 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.

Three-Dimensional Shapes. This page examines the properties of three-dimensional or ‘solid’ shapes. A two-dimensional shape has length and width. A three-dimensional solid shape also has depth. Recreational Mathematics. Math.
