Question

The formula for the surface area of a cube is SA = 6s2, where s is the length of one side of the cube. What is the surface area of the cube shown below?



9.375 sq ft
56.25 sq ft
36 sq ft
15 sq ft

Answer 1

We recall the formula for the surface area of a cube

The surface area of a cube $=6s^{2}$

Given:

$s=\sqrt{6} ft$

S.A.$=6.(6)$

$=36 sq ft$

Option 3 is correct

Answer 2

Given; The formula for the surface area of a cube is SA = 6s2, where s is the length of one side of the cube.

To Find; The surface area of a cube

Solution ;

Surface area =6s^2

a^2=6s^2

The surface area of cube=6a^2

6*6=36sq ft

Hence c option is correct
