Question

What is the base area of Box 3? x2 + x

Answer 1

The base area of box 3, whose length is x²+x is x⁴+x²+2x³

Cube is a 3d figure whose all sides are equal and has 8 vertices , 6faces .

Volume=a³

Surface area=6a²

Base area=a²

a=x²+x

base area of a square =a²

                                       =(x²+x)²

                                        =x⁴+x²+2x³

Therefore, the base area of box 3, whose length is x²+x is x⁴+x²+2x³
