Calculate the volume of the shell of a quadrilateral prism with a rhombus-shaped base with dimensions a=6cm, va=40mm. The height of the prism is 81 mm.

Correct answer:

P =  242.4 cm2

Step-by-step explanation:

a=6 cm v=40 mm cm=40:10  cm=4 cm h=81 mm cm=81:10  cm=8.1 cm  S1=4 a h=4 6 8.1=5972=194.4 cm2 S2=a v=6 4=24 cm2  P=S1+2 S2=194.4+2 24=242.4 cm2
