5th Grade Volume of Rectangular Prisms Quiz: 10 Questions with Explanations

One layer has \(3 \times 2 = 6\) cubes and there are 2 layers, so \(6 \times 2 = 12\). Adding \(3 + 2 + 2 = 7\) is a common mistake.

\(5 \times 4 \times 3 = 60\). Multiplying only two edges gives 20, which is the base area.

One layer has \(3 \times 2 = 6\) cubes, and there are 4 layers, so \(6 \times 4 = 24\).

V = B × h = \(30 \times 4 = 120\). Adding gives 34, and dividing gives 7.5.

The base area is \(6 \times 4 = 24\) and \(96 \div 24 = 4\). Dividing by only one edge gives 16 or 24.

Prism A is \(5 \times 2 \times 3 = 30\) and prism B is \(2 \times 2 \times 1 = 4\). Add: \(30 + 4 = 34\).

Volume counts cubes, so it is measured in cubic units like cubic inches. Square inches measure area.

\(15 \times 8 \times 10 = 1{,}200\). Adding the edges gives 33.

\(5 \times 5 \times 5 = 125\). Multiplying \(5 \times 3\) gives 15, a mistake.

Add the two volumes: \(48 + 36 = 84\). Subtracting gives 12, and multiplying gives 1,728.
