Question

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

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 :

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

$\tt : \implies Total \: surface \: area = 6 (7 \: inches)^{2}$

$\tt : \implies Total \: surface \: area = 6 \times 49 \: inches^{2}$

$\tt : \implies Total \: surface \: area = 294 \: inches^{2}$

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