In this activity, we will learn how to calculate the volumes of cuboids and prisms.
Find the volume of this cuboid.
The volume of a cuboid is found by multiplying length x width x height.
Volume = 7 x 5 x 2 = 70 cm3
Note that in the shape below, the side labelled 6 is the length of the top side ( the bottom length would be 6 + 2 = 8)
This prism is made up of two cuboids with dimensions:
4 x 2 x 8 (volume = 64)
6 x 1 x 8 (volume = 48)
The volume of the prism can be found by adding together the volumes of the cuboids.
Volume of prism = 64 + 48 = 112 units3
