Use the formulas V=s❸ andA=6s❷ to calculate the volume and surface area of the cube That is 2.5 in. on each side.
V = s^3
SA = 6*s^2
Just substitute the given length of one side of the cube.
V = (1.5)^3 = ? (units in cubic inches)
SA = 6*(2.5)^2 = ? (units in square inches)
*sorry I mean, V = (2.5)^3
To calculate the volume and surface area of a cube, you can use the given formulas:
V = s³ (volume of a cube)
A = 6s² (surface area of a cube)
Given that the length of each side is 2.5 inches, we can substitute this value into the formulas to find the volume and surface area.
1. Calculating the volume:
V = s³
= (2.5)^3
= 2.5 × 2.5 × 2.5
= 15.625 cubic inches
Therefore, the volume of the cube is 15.625 cubic inches.
2. Calculating the surface area:
A = 6s²
= 6 × (2.5)^2
= 6 × 2.5 × 2.5
= 6 × 6.25
= 37.5 square inches
Thus, the surface area of the cube is 37.5 square inches.
To summarize:
- The volume of the cube with a side length of 2.5 inches is 15.625 cubic inches.
- The surface area of the same cube is 37.5 square inches.
