Question

Question 4(iii)
Obtain the volume of rectangular boxes with the following length, breadth and height respectively:
$xy,2x^{2}y,2x{y}^2$

Answer 1

Volume of rectangular box = $\text{length}\times \text{breadth}\times \text{height}$ $=xy\times 2x^{2}y\times 2x{y}^2=(1\times 2\times 2)(x\times x^2\times x\times y\times y\times y^2)$
$=4x^4{y}^4\text{cubic units}$
