This document discusses how to calculate the volume of various solids. It explains that volume measures the amount of space inside three-dimensional figures and can be calculated using the area of the end face multiplied by the length for solids with parallel faces and constant cross-sections, such as cuboids, prisms, and cylinders. Various examples are provided for calculating the volumes of specific solids like cubes, cuboids, cylinders, pyramids, cones, and spheres.

VOLUME for Solids

2. • A solid is three-dimensional figure. Eg: a stone and a
cube.
• The volume of solids is a measure of the amount of space
inside these figures. In otherwords, the volume of a solid
is the measure of how much space an object takes up.
• Solids like cuboids, prisms, and cylinders all have parallel
faces and constant cross-sections. In each case, their
volume, V, can be calculated using:
V= area of end face x length
• Different figures lead to different computation.

3. Triangular Prism

4. Remember!!
• Volume of a right uniform solid, V= Ah,
Where A =area of the cross-section of the right uniform
solid
and h= the length, height or thickness of the right
uniform solid
