Step-by-step explanation:
Volume and Surface area of Sandcastle description and calculation
Composite volume calculation summary:
add three of each hexagonal shape, three rectangular prisms, subtract one
“door” and one semicircular prism.
model: V = 3*124.71in³+3*13.86in³+3*144in³-16in³-12.57in³
V = 819.14in³
sand: V = 3*15.59ft³+3*1.73ft³+3*18ft³-2ft³-1.57ft³
V = 102.39ft³
