Question

the surface area of a cube is 384 CM square find the length of an edge and volume of the cube

Answer 1

A = 6a²
384 = 6 a²
384/6 = a²
a= √64
a = 8 cm

v = a³
v = 8³
v = 512cm³


mark brainliest, if it helps, Thanks.

Answer 2

Heya,

TSA = 384^2

TSA = 6a^2
384 = 6a^2
384/6 = a^2
64 = a^2
√64 = a
√8 × 8 = a
8 = a

Volume = a^3
Volume = 8 × 8 × 8
Volume = 512^3

Hence,
Length = 8cm
Volume = 512^3

Hope my answer helps you :)
