Question

What is the volume of the right rectangular prism? 21 cm3 42 cm3 120 cm3 240 cm3

Answer 1

Answer: Last Option

$V=240\ cm^3$

Step-by-step explanation:

The formula for calculating the volume of a prism is:

$V = lwh$

Where l is the length, w is the width and h is the length.

In this case we know that:

$l=10\ cm\\w=3\ cm\\h=8\ cm$

Therefore:

$V =10*3*8$

$V=240\ cm^3$

Answer 2

Answer: $240\ cm^3$

Step-by-step explanation:

The volume of a right rectangular prism is given by :-

$\text{Volume}=lwh$ , where l is length , w is width and h is the height of the right rectangular prism.

In the given picture , we have the length of the prism = 10 cm

Width of the prism = 3 cm

Height of the prism = 8 cm

Then , the volume of a right rectangular prism will be :-

$\text{Volume}=10\times3\times8\\\\\Rightarrow\ \text{Volume}=240\ cm^3$
