Answer:
a) 24 square feet
b) $12
Step-by-step explanation:
You want to make a retangular prism out of cardboard. The base is 3 feet by 4 feet. The height is 2 feet. You have $5.00 and cardboard costs .10 per square foot.
a) What is the surface area of the rectangular prism?
Length × Width × Height
3 feet × 4 feet × 2 feet
= 24 square feet
b).How much will it cost to make the rectangular prism out of cardboard?
1 ft² = $0.5
24 ft² = x
Cross Multiply
x = 24ft² × $0.5/1 ft²
x = $12
It would cost $12 to make the rectangular prism out of the cardboard. You do not have sufficient money to make it
