Answer:
d = 3.46 units
Explanation:
The diagram below is a rectangular prism . The volume of the prism is given as 99 units³ .
volume of a rectangular prism = Length × width × height
height = 5.2 units
volume = 99 units³
length = 5.5 units
width = d
let us find the width which is d
volume = L × w × h
99 = 5.5 × d × 5.2
99 = 28.6d
divide both sides by 28.6
d = 99/28.6
d = 3.4615384615
d = 3.46 units
