Question

If the area of a face of a cube is 15cm2 then the total surface area of the cube is __________ cm2.

Answer 1

Step-by-step explanation:

A cube has 6 faces.

Area of one face=15 cm^2

Surface area of cube= 90 cm^2

Answer 2

Step-by-step explanation:

Given that

Area of a face of a cube is 15cm sq

To find

Total surface area

Solution

As we know cube has the 6 faces

hence its total surface area can be calculate by multiplying face area by 6

$total \: surface \: area = 6 \times area \: of \: a \: face \\ = 6 \times 15 \\ = 90 {cm}^{2}$

hence total surface area of cube is 90 cm sq.
