Question

The surface area of a cube whose volume is 64m is

Answer 1

Answer:

let the side of the cube be a .

thus ,  volume of a cube = a * a * a

surface area of a cube = 6 * a * a

volume = 64 thus , a * a * a = 64

a * a * a = 4 * 4 * 4

thus , a = 4 m

surface area = 6 * a * a

since a = 4

surface area = 6 * 4 *4

= 96 m2

hope u will understand it

Step-by-step explanation:

Answer 2

Answer:96

Step-by-step explanation:

64m^3=(4×4×4)m^3=4^3

total surface area=6a^2

6×4×4=6×16=96
