Answer:
4.5 Cubic Feet
Step-by-step explanation:
1. You want to find the volume of the box. (Length x width x height)
2.5 x 2 x 1.5 = 7.5
2. The present has a volume of 3 cubic feet, so you would subtract that from the volume of the box.
7.5 - 3 = 4.5
3. The volume of the empty space in the box is 4.5 cubic feet.

Answer:
45cm
Step-by-step explanation:
Volume of a sphere = 4/3πr³
Volume of an hemisphere = 1/2 of volume of a sphere
Volume of hemisphere = 1/2{4/3πr³}
Volume of hemisphere = 2/3πr³
Given
Volume of the hemisphere = 60,750πcm³
60,750π = 2/3πr³
π cancels out
60,750 = 2/3r³
Multiply both sides by 3
2r³ = 60,750×3
2r³=182,250
Divide both sides by 2
r³ = 91,125
Find the ∛ of 91,125 to eliminate the cube on r
r = ∛91,125
r = 45cm
