In this lesson, we will learn how to find volumes of cuboids, then composite solids made of cuboids, and then prisms.

Q1:

Maged made a cardboard house at school. The lower part of the house is a rectangular prism and the upper part a triangular prism. Find the volume of the house.

Q2:

Each of these rectangular prisms is made up of unit cubes. Which has a volume of 30 cubic units?

Q3:

How many cubes with a side length of 1 2 does it take to fill the given prism?

Q4:

Work out the volume of the right triangular prism shown.

Q5:

The solid shown is a rectangular prism with a triangular prism cut out along its length. Work out the volume of the solid.

Q6:

Given that the volume of each small cube is 1 cubic unit, find the volume of this prism.

Q7:

Given that each unit cube has a side length of 1, find the volume of the given prism.

Q8:

Shady and Nada are calculating the volume of a rectangular prism with length 18 m, height 11 m, width 4 m. Shady said that the volume is 792 m^{3}, and Nada said it was 44 m^{3}. Who is correct?

Q9:

The solid shown is formed from two rectangular prisms. Work out the volume of the solid.

Q10:

Work out the volume of the trapezoidal prism shown.
