3 in.
What is the surface area of the object in
square inches?​

Answer 1

Given:-

• The object below is made with six identical cubes. Each cube edge is 3 inches long.

To Find:-

• Surface Area of the object in square inches.

Formula Used:-

• ${\boxed{\bf{TSA\:of\:Cube=6a^2}}}$

Here, a = Side.

Solution:-

$\sf :\implies\:TSA\:of\:Cube=6a^2$

$\sf :\implies\:TSA\:of\:Cube=6\times 3^2$

$\sf :\implies\:TSA\:of\:Cube=6\times 9$

$\sf :\implies\:TSA\:of\:Cube=54\:inches^2$

Surface Area of 6 identical cubes = 6 × 54

Surface Area of 6 identical cubes = 324 in².

Hence, The Surface Area of the object is 324 inches².
