Answer:
1651.06 m³
Step-by-step explanation:
the volume of the whole block is base area times height :
Vb = 10 × 12 × 18
but we have to deduct the volume of the removed central cylinder.
the volume of the cylinder is again base area times height :
Vc = pi×r² × 18 = pi×3² × 18 = pi×9×18
so, the volume of the object is
V = Vb - Vc = 2160 - 508.94 = 1651.06 m³
