Answer:
The volume of platform
= 11 ft³
Step-by-step explanation:
The height of the Platforms are
The food prep area = 5 ft
Storage shelf = 6 ft
Side of rectangle = b width of platform = d
Therefore area of platform = b·d
Volume of the food prep area platform = Area × height = 5 b·d ft³
Volume of the storage shelf platform = Area × height of storage shelf platform = 6 b·d ft³
Therefore the total volume = Volume of food storage platform + volume of storage shelf platform = 5 b·d ft³ + 6·b·d ft³ = 11·b·d ft³
