Question

Item 8

A rectangular prism has a length of 312 m, a width of 412 m, and a height of 2 m.



Which expressions can be used to find the volume of the prism?



Select each correct answer.

Answer 1

• Option A
• Option D

Explanation:

We know that:

• Volume of rectangular prism = L x B x H
• L = 3 1/2 m
• B = 4 1/2 m
• H = 2 m

Solution:

• L x B x H = 3 1/2 x 4 1/2 x 2
• => 7/2 x 9/2 x 2
• => 7/2 x 9
• => 63/2 m³

Looking at the options, we can say that Option A and D are correct because if we simplify them, they will give the same result.

Hoped this helped!

Answer 2

Volume is length x width x height.

You can use 3 1/2 x 4 1/2 x 2

And 3 1/2 x 4 1/2 = 15 3/4 so you can use

15 3/4 x 2

A and D are both correct
