Question

Volume of a rectangular box with $l=b=h=3x$ m is .

• A. $16x^3{m}^3$
• B. $9x^3{m}^3$
• C. $27x^3{m}^3$
• D. $8x^3{m}^3$

Answer 1

The correct option is C $27x^3{m}^3$

Given: Length = breadth = height = 3x m.
Volume of a rectangular box = length $\times$ breadth $\times$ height
$V=(3x\times 3x\times 3x)m^3$
$\Rightarrow V=27x^3{m}^3$
