Question

Find the surface area of the cube

Answer 1

Answer:

24 cm²

easy way to find surface area of a cube.

use the formula: 6a²

$\hookrightarrow 6(2)^2$

$\hookrightarrow 6(4)$

$\hookrightarrow24$

Answer 2

Solution:

We know that:

$\space\ Surface \space\ area \space\ of \space\ cube=\s Area \space\ of \space\ it's \space\ faces$

This means that:

$\space\ Surface \space\ area = [(2)(2)] + [(2)(2)] + [(2)(2)] + [(2)(2)] + [(2)(2)] + [(2)(2)]$

Simplify the expression to find the surface area.

Simplifying the expression:

$[(2)(2)] + [(2)(2)] + [(2)(2)] + [(2)(2)] + [(2)(2)] + [(2)(2)] \\\\\ [4] + [4] + [4] + [4] + [4] + [4]\\\\ 4[6] \\\\ 24 \space\ cm^{2}$

Hence, the surface area is 24 cm².
