Truncated 43851

The pit has the shape of a regular truncated 4-sided pyramid, the base edges of which are 14m, 10m, and the depth is 6m. Calculate how many m3 of soil were removed when we dug this pit.

Correct answer:

V =  872 m3

Step-by-step explanation:

a=14 m b=10 m  h=6 m  S1=a2=142=196 m2 S2=b2=102=100 m2  S=S1+S1 S2+S2=196+196 100+100=436 m2  V=31 h S=31 6 436=872 m3
