Answer:
we have:
=> r²h = 10.18 = 9.20 = 5.36 = 6.30 = 4.45 = 12.15
=> only r²h = 5.36 satisfy the problem
=> h = 5
h = 5 r = 6
h = 5 r = 6=> d = 12
Answer:
is the volume in terms of side a
Step-by-step explanation:
Given that you I built a storage shed in the shape of a rectangular box on a square base. The material that I used for the base cost $4 per square foot, the material for the roof cost $2 per square foot, and the material for the sides cost $2.50 per square foot; and I spent $450 altogether on material for the shed.
Let a be the side of square and h be the height
Total cost of materials = cost for floor + cost for roof + cost for sides
= area of floor (4) + lateral area (2.50)+roof area (2)
Now coming to volume
Volume = V = lbh =
