Question

What is the volume of a rectangular prism with the dimensions: base 2/1 2, height 1/1 2, and length 3/1 2?

A.) 13/1 8
B.) 8/1 2
C.) 7/1 2
D.) 6/9 16

Answer 1

A) 13 ⅛

Explanation:

2½ × 1½ × 3½

(5/2) × (3/2) × (7/2)

105/8

13 ⅛

Answer 2

A

Explanation:

The volume of a rectangular prism is:
`V=lwh` , where
`l` is the length, w is the width, and h is the height.

Here, we are given all three lengths, so we plug them into the formula to find V: V =
`(2 (1)/(2) )*(1 (1)/(2) )*(3 (1)/(2) ) = (5)/(2) * (3)/(2) *(7)/(2)=(105)/(8) =13(1)/(8)`

Thus, the answer is A, 13 1/8.

Hope this helps!
