Question

The surface area of a cube is 864 sq cm. What is the length of each side of the cube?

Answer 1

Since total surface area = 864 cm2

Tsa of cube= 6 a2 so 864/6 = a2 144 = a2 a=√144 so a= 12 cm hence each side of cube is 12 cm

Answer 2

Answer:

12

Step-by-step explanation:

surface area =6l*l

so,864=6*l*l

864/6=l*l

=144=l*l

√144=12

so one side is 12
