Question

Find the surface area of this cube: 3.2m 3.2m 3.2m​

Answer 1

..the area of ​​the total surface is equal to 6 times the "square" of its edge.

Formula: 6 times the area of ​​a square = 6 a² (“a” being the length of an edge)

Edge = 3.2m

A = 6*3.2²=61.44m²

Explanation:

Answer 2

`\mathrm{The\ formula\ for\ the\ surface\ area\ of\ any\ cube\ with\ length}\ l\ \mathrm{is:\ 6}l^2.\\\mathrm{Here,\ length\ of\ cube(}l)=3.2\mathrm{m}\\\therefore\ \mathrm{Surface\ area=6}l^2=6(3.2)^2=61.44\mathrm{m^2}`
