Question

Obtain the volume of rectangular boxes with the following length, breadth and height respectively.

$5a,3a^2,7a^4$

Answer 1

Given:

length of rectangular box, $l=5a$

breadth of rectangular box, $b=3a^2$

height of rectangular box, $h=7a^4$

Therefore,

Volume of rectangular boxes,

$$\begin{gathered} V=l\times b\times h \\ V=5a\times 3a^2\times 7a^4 \\ V=105a^7 \end{gathered}$$

Hence, Volume of the rectangular boxes is $105a^7$
