Answer:
Step-by-step explanation:
From the question we are told that
Edges of 8 feet, 4 feet, and 1/2 foot
Generally the volume V_p of the right rectangular prism is mathematically represented as


Generally volume of the cube V_c is mathematically given as


Therefore total number of cubes is given as



10x+25 (expressions don't have equal signs)
Im not understanding what you are asking
In(xy) = e^(x+y)
(xy)'/xy = (x+y)' e^(x+y)
(x'y + xy')/xy = (1+y') e^(x+y)
(y + xy')/xy = (1+y')e^(x+y) and simplify
Hope this helps
You probably know that for
, we have

Your sum starts at
, so it's equivalent to

so the answer is A.
