Answer:
17. 2,336 ft²
18. V = 6,720 ft³
Explanation:
17. Surface area of the tent not including the floor = area of the 2 triangular bases + area of the 2 rectangular side faces
= 2(½*bh) + 2(L*W)
Where,
b = 14 ft
h = 24 ft
L = 40 ft
W = 25 ft
Substitute
Area = 2(½*14*24) + 2(40*25)
Area = 336 + 2,000
Area = 2,336 ft²
18. Volume of circus tent = volume of triangular prism = ½*b*h*l
Where,
b = 14 ft
h = 24 ft
l = 40 ft
Substitute
V = ½*14*24*40
V = 6,720 ft³
