Question

Mark the correct alternative in the following question:

If the lengths of edges of a cuboid are 2x, 3y and 4xy, then its volume is

(a) 24xy (b) 9x²y² (c) 24x²y² (d) 6x²y²

Answer 1

As,

$$\begin{gathered} \mathrm{Volume}\mathrm{of}\mathrm{the}\mathrm{cuboid}=2x\times 3y\times 4xy \\ =\left(2\times 3\times 4\right)\times \left(x\times x\right)\times \left(y\times y\right) \\ =24x^2{y}^2 \end{gathered}$$

Hence, the correct alternative is option (c).
