Answer
1. a. The volume of the pyramid.
b. b = 10m and h = 20m
c. Formula: V = b^2 x h / 3
d. V = 10m x 10m x 20m / 3
e. V = 2,000 cu.m / 3
V = 666.67 cu.m
The volume of the pyramid with the square base is 666.67 cubic meters.
2. a. The volume of rectangular pyramid
b. b = 12 cm and 24 cm, h = 16 cm
c. Formula: V = lwh/3
d. V = 12cm x 24cm x 16cm /3
e. V = 4,608 cu.cm / 3
V = 1,536 cu.cm
The volume of the pyramid is 1,536 cubic centimeters.
3. a. The volume of ghe air enclosed bh the tent.
b. r = 5cm and h = 25cm
c. Formula: V = TT r2 h / 3
d. V = 3.14 (5cm x 5cm) (25cm) / 3
e. V = 1,962.4 cu.cm / 3
V = 654.17 cu.cm
The volume of the air enclosed by the tent is 654.16 cubic centimeters
4. a. The volume of water needed to fill the bowl.
b. r = 15cm
c. V = 4/3 TT r3
d. V = 4/3 (3.14) (15cm x 15cm x 15cm)
e. V = 4/3 (3.14) (3,375 cu.cm)
V = 42,390 cu.cm / 3
V = 14,130 cu.cm
14.130 cubic centimeters of water needed to fill the bowl
Find the volume of the following figure:
1. V = 1,356.48 cu.cm
2. V = 600 cu.m
3. V = 769.3 cu.cm
4. V = 904.32 cu.cm
5. 7,850 cu.cm
Hope it helps
