Answer: False
The Fermi Process is a fast way to calculate an estimate (usually done with mental math or math you can do on the back of an envelope or napkin). It's unlikely you'll get the exact answer, though you should be fairly close. To make the math more simple, rounding is done.
I would go with Either E or A
Answer:
solution given:
volume of lower one[V1]=l×b×h=1.5×0.5×0.5=0.378m³
volume of upper one [V2]=l×b×h=1×0.5×(0.75-0.5)=
0.125m³
total volume=V1+V2=0.378m³+0.125m³=0.503m³
0.503m³ is your answer
7 1/2 x 3 3/4 x 2, to get the answer. The answer is
56 1/4 feet squared
