Question

What is the surface area of the cube below

Answer 1

Answer:

Option D is correct

Surface area of a cube is 294 square units

Step-by-step explanation:

Surface area of a cube is given by:

$S = 6a^2$ square unit

where

S is the surface area of a cube

a is the length of edge of a cube.

From the given figure, we have;

a = 7 units

then;

$S = 6(7)^2 = 6(49) = 294$ square units

Therefore, the Surface area of a cube is 294 square units
