Question

Example 9: The volume of a cuboid is 27 cm cube .Find its surface area​

Answer 1

Step-by-step explanation:

Let the length of each side of the cube= 6

$now \: the \: volume \: of \: cube = {27m}^{3} \\ = {s}^{3} = 27 \\ = s = \sqrt[3]{27} \\ = \sqrt[3]{3 \times 3 \times 3 } = 3cm \\ = surface \: area \: of \: the \: cube = {6s}^{2} \\ = 6 \times ( {3}^{3} ) \\ = 6 \times 9 \\ = {54cm}^{2}$
