Volume of the box = Area of Square base × depth of the box Calculate the volume of the box if it is 10cm deep. = Area of any face × thickness of the face. Hence: Volume of a cuboid = Area of base × height The volume of a cuboid = length × breadth × height It has length, width (breadth) and height (thickness). Volume of the container not filled liquidĪ cuboid is also called a rectangular prism. (b) Volume of the cube = S 3 = 25 x 25 x 25 Volume of liquid in the container = 625 x 15 = 9375cm 3 (a) Base area of the container = 25 x 25 = 625cm 2 (b) Calculate the volume of the container not filled with liquid. (a) Calculate the volume of liquid in the container. The depth of the liquid in the container is 15cm as shown in the diagram below. A container in the shape of a cube is used to store a liquid. Solution: Volume of a cube = length × height × width = s × s × s = 4 × 4 × 4 = 64 cm3 NOTE: The above formula can be used to find the edge of a cube when the volume is given. Calculate the volume of a cube of an edge 4cm. The Volume of a Cube If one edge of a cube is s unit long, then Volume of a cube = side × side × side i.e. Therefore, volume is measured in cubic units. The cube is used as the basic shape to estimate the volume of a solid. The Volume of Cubes and Cuboids The volume of a solid is a measure of the amount of space it occupies. It has only one spherical face in its entire surface.a pyramid with a triangle as its base is a triangular based pyramid, etcĮxamples: Sharpened point of a crayon or pencil, mound of groundnut, ice-cream, etc.

Pyramids are classified according to their bases and named after the shape of their bases e.g. They have 6 equal faces in the shape of a shape.Ī pyramid is a solid figure whose base is a polygon and whose lateral faces (surfaces) are triangles with a common vertex called a pyramid.A cube is a special cuboids which has all its edges (sides) equal in length.Examples: A cube of sugar, maggi cube, dice, etc.
