Astudent wrote this statement “a triangular prism has a height of 15 inches and a base area of 20 square inches. the volume of the prism is 300 square inches.” identify and correct the error

For this case, what you must keep in mind is that the volume of a triangular prism is the product of the area of the base by height.
 We observed that:
 V = (15) * (20) = 300
 The numeric value is correct.
 However, the units are not because the volume is expressed in:
 units ^ 3
 
 "a triangular prism has a height of 15 inches and a base area of 20 square inches. The volume of the prism is 300 CUBIC inches. "

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
