Answer:
140.6 ft³
Step-by-step explanation:
The volume remaining is calculated as
V = volume of block - volume of cylinder
= s³ - πr²h ( s is side of block, r is radius, h is height )
Here s = 6, r = 4 ÷ 2 = 2, h = 6 , then
V = 6³ - (π × 2² × 6)
= 216 - (π × 4 × 6)
= 216 - 24π
≈ 140.6 ft² ( to the nearest tenth )
