Question

find the volume and total surface area of a cube whose each edge is 8cm

Answer 1

we know that
Volume of a cube =side×side×side
Volume of a cube=8×8×8=216cm^3
Total surface area of the cube=$6 \times side^{2}$
Total sur area=384cm^2

Answer 2

Heya...

Edge (a) = 8cm

➡Total surface area = 6a^2
Total surface area = 6(8)^2
Total surface area = 6(64)
Total surface area = 384cm^2

➡Volume = a^3
Volume = 6^3
Volume = 216cm^3
