The formula for the volume of a right triangular pyramid is V = (1/3) * base area * height.
Plugging in the values given:
V = (1/3) * 12 cm² * 8 cm
V = (1/3) * 96 cm³
V = 32 cm³
Therefore, the correct answer is C) 32 cm³.

Question
A swimming pool is shaped like a right rectangular prism with length 20 feet, height 8 feet, and width 15 feet. If the pool's water line is one foot below the top of the pool, find the volume of water in the pool.
Responses
A 2,000 cubic feet2,000 cubic feet
B 2,100 cubic feet2,100 cubic feet
C 2,250 cubic feet2,250 cubic feet
D 2,400 cubic feet
The volume of a right rectangular prism is calculated as V = length * width * height.
Given:
Length = 20 feet
Height = 8 feet
Width = 15 feet
Volume of the entire pool:
V = 20 ft * 15 ft * 8 ft
V = 2400 cubic feet
The volume of the portion of the pool above the water line is:
Volume above water line = 20 ft * 15 ft * 1 ft (height above water line)
Volume above water line = 300 cubic feet
Therefore, the volume of water in the pool is:
Volume of water = Total volume - Volume above water line
Volume of water = 2400 cubic feet - 300 cubic feet
Volume of water = 2100 cubic feet
Therefore, the correct answer is B) 2,100 cubic feet.
