Answer:
volume remaining ≈ 153 in³
Explanation:
the volume remaining after the cylinder has been drilled is
volume of prism - volume of cylinder
volume of prism = lbh ( l is length, b is breadth, h is height )
= 5 × 7 × 5
= 175 in³
volume of cylinder = πr²h ( r is the radius and h the length of cylinder )
= π × 1² × 7
= 7π in³
volume remaining = 175 - 7π
= 175 - 21.99
= 153.01
≈ 153 in³ ( to the nearest cubic inch )
