Question

A metal cube has volume of 64cm3.it has to be painted on all its faces.find the total area of the faces that will be coated with paint

Answer 1

Step-by-step explanation:

$volume = {s}^{3} \\ 64 = {s}^{3} \\ s = 4$

$total \: surface \: area \: = 6 \times {s}^{2} \\ total \: surface \: area \: = 6 \times {4}^{2} \\ total \: surface \: area \: = 6 \times 16 \\ total \: surface \: area \: = 102 {cm}^{2}$

Total area of coated with paint = 102cm^2
