Question 11

Volume of a rectangular box (cuboid) with length = 2ab, breadth = 3ac and height = 2ac is
a) $12a^{3}b{c}^2$
b) $12a^{3}bc$
c) $12a^{2}bc$
d) $2ab+3ac+2ac$

Answer 1

a) $12a^{3}b{c}^2$
$\to$​​​​​​​We know that, volume of a cuboid = Length $\times$ Breadth $\times$ Height = $2ab\times 3ac\times 2ac$
$=(2\times 3\times 2)ab\times ac\times ac=12\times a\times a\times a\times b\times c\times c=12a^{3}b{c}^2$
