the height of the rectangular prism is 2cm
Step-by-step explanation:
the question says
volume of a rectangular prism equals 80cm³
the length of the rectangular prism is equals to 20cm
the width of the rectangular prism equals to 2cm
the height of the rectangular prism is unknown ?
solution
to find the height we will use the fomular of finding the volume of a prism
volume of a rectangular prism = length × width × height
80 = 20 × 2 × h
80 = 40h
divide both sides by 40
80/40 = 40h/40
2 = h
h = 2cm
therefore the height of the rectangular prism is 2cm
