Question

To find the total surface area of a cube, you use the

expression 652. What is the surface area of a cube
with a side length of 7 inches?

Answer 1

`\Large \underline{\tt Given} :`

• Side of cube = 7 inches

`\\`

`\Large \underline{\tt To \: Find} :`

• Total surface area = ?

`\\`

`\Large \underline{\tt Solution} :`

As, we have side of cube is 7 inches.

So, to find total surface area, we have a formula :

`\underline{\boxed{\bf{Total \: surface \: area_((cube)) = 6(side)^(2)}}}`

`\tt : \implies Total \: surface \: area = 6 (7 \: inches)^(2)`

`\tt : \implies Total \: surface \: area = 6 * 49 \: inches^(2)`

`\tt : \implies Total \: surface \: area = 294 \: inches^(2)`

`\\`

Hence, Total surface area of given cube is 294 inches².
