Question

surface area of a cube is equal of 294msquare .find the volume of the cube .

Answer 1

hope it helps,

mark as brainlist please.

The surface area of a cube is found by multiplying the area of one side by 6 (A cube has six faces)
The area of one face must therefore be = Surface area / 6
= 294 / 6
= 49 square cm
Area of a square = length x length
ie length = square root(area of square)
= Square root(49)
=7 cm
Volume of a cube = (length x length x length)
= 7 x 7 x 7
= 343 cubic cm

Answer 2

hola!

===============================================================

Surface area of a cube is equal of 294msquare .find the volume of the cube .

===========================================================

surface area if cube = 294

6a² = 294

a² = 294/6

a² = 49

a = √49

a = 7m

now volume of cube = side³

=> (7)³

=> 343m³

hope it helps u
