Question

jane builds a ramp made of a triangular prism and a rectangular prism. what is the volume of the ramp? 1 m 4 m 2 m 3.5 m 7.5 m³ 15 m³ 28 m³ 11.5 m³

Explanation:

Step1: Calculate volume of rectangular prism

$V_{rectangular}=l\times w\times h = 4\times2\times1=8$ ($m^{3}$)

Step2: Calculate volume of triangular prism

$V_{triangular}=\frac{1}{2}\times base\times height\times length=\frac{1}{2}\times2\times1\times3.5 = 3.5$ ($m^{3}$)

Step3: Calculate total volume

$V = V_{rectangular}+V_{triangular}=8 + 3.5=11.5$ ($m^{3}$)

Answer:

$11.5\ m^{3}$
