What is the surface area of a rectangular prism that has a length of 9 feet, a width of 5 feet, and a height of 7.5 feet?
never [62]
A suitable formula for the surface area of a rectangular prism is ...
  A = 2(LW +H*(L +W))
Filling in the given information, we have
  A = 2((9 ft)*(5 ft) +(7.5 ft)*(9 ft +5 ft))
  A = 2(45 ft² +(7.5 ft)*(14 ft)) = 2(150 ft²)

The surface area of the rectangular prism is 300 ft².

Answer:

226.8cm^2

Step-by-step explanation:

A=pir^2

24/4 = 6 (radius of small circles)

pi6^2= 113.097335529 times 2 (because theres 2 of them)

=226.8

24/2 = 12 (radius of big circle)

pi12^2= 452.4 minus 226.8 (to get the leftover space)

=226.8
