Explanation:
The volume of the cylinder is
V2 = (pi)r^2L
= (3.14)(12.5 xm)^2(50 cm)
= 24531.3 cm^3
The volume of the half cylinder is
V3 = (1/2)(24531.3 cm^3)
= 12265.7 cm^3
If V1 is the volume of the prism then the total volume of the storage chest is
V = V1 + V2 + V3
= 37500 cm^3 + 24531.3 cm^3 + 12265.7 cm^3
= 74297.0 cm^3
