Question

A rectangular prism has a length of 5 cm, a width of 2 1/2cm and a height of 1 1/2 cm Which expressions can be used to find the volume of the prism?

Select each correct answer.



5∙2 1/2∙1 1/2
12 1/2∙1 1/2
1 1/2(5+2 1/2)
1/2(12 1/2∙1 1/2)

Answer 1

5 x 2 1/2 x  11/2 is your answer

Answer 2

Answer:
`5\cdot 2(1)/(2)\cdot 1(1)/(2)`

Explanation:

The volume of the rectangular prism is given by :-

`\text{Volume}=length\cdot width\cdot height`

Given: Length = 5 cm

Width =
`2(1)/(2)` cm

Height=
`1(1)/(2)` cm

Therefore, The expression for volume of the given rectangular prism will be :-

`\text{Volume}=5\cdot 2(1)/(2)\cdot 1(1)/(2)`
