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 =
Answer:
area of trapizoid=49 unit^2
Step-by-step explanation:
area of trapizoid=0.5(x+y)h
where, x=parallel side=3units
y=parallel side =11 units
h=distance between two parallel sides
area of trapizoid=0.5(x+y)h..............(1)
put x=3 units,y=11 units and h=7 in equ (1)
area of trapizoid=0.5(3+11)7
area of trapizoid=
area of trapizoid=49 unit^2 answer
