The expression 6x2 gives the surface area of a cube, and the expression x3 gives the volume of a cube, where x is the length of one side of the cube. Find the surface area and the volume of a cube with a side length of 4 meters.
The expression 6x2 gives the surface area of a cube, and the expression x3 gives the volume of a cube, where x is the length of one side of the cube. Find the surface area and the volume of a cube with a side length of 4 meters.
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 .
