Question

find the edge of a cube whose surface area is 294cm​

Answer 1

Answer:

Hey mate.

=======

Given, The surface area of a cube is 294 cm^2

We Know,

The surface area of a cube = 6 (side)^2

=> 294 = 6 ( side ) ^2

=> 294 / 6 = (side) ^2

=> 49 = (side)^2

=> 7 = Side

Thus,

Volume of a cube = (side)^3

= (7)^3

= 343 cm^3

Hope it helps !!

Answer 2

Answer:

Side of the cube = 7 cm

Step-by-step explanation:

For a cube with side "a", the total surface area = 6a^2

For the given cube with side "a", total surface area = 294

=> 6a^2 = 294

=> a^2 = (294/6)

=> a^2 = 49

=> a = 7
