surface area of the cube is 96m² and the volume is 64m³

Step-by-step explanation:

Surface area of the cube = 6x²

x is the side length

Given

x = 4metres

Surface area of the cube  = 6(4)²

Surface area of the cube = 6(16)

Surface area of the cube  = 96m²

Volume of the cube = x³

Volume of the cube = 4³

Volume of the cube = 64m³

Hence the surface area of the cube is 96m² and the volume is 64m³

It should be 486 m² and 729 m³

Step-by-step explanation:

x = 9

6 (9) ²

9 x 9 = 81

6 x 81 = 486

(9)³ = 729

Surface of a cube = S(x)

S(x)=6x²

S(2m)=6(2m)²=6(4m²)=24m²

The surface of this cube is 24m².

Volume of a cube = V(x)

V(x)=x³

V(2m)=(2m)³=8m³

The volume of this cube is 8m³ .
