Answer:
2280 ft^2
Step-by-step explanation:
A rectangular prism has 6 faces. Each pair of opposite faces is congruent.
surface area = 2LW + 2LH + 2WH
surface area = 2(24 ft)(20 ft) + 2(24 ft)(15 ft) + 2(20 ft)(15 ft)
surface area = 960 ft^2 + 720 ft^2 + 600 ft^2
surface area = 2280 ft^2
multiply the 1st by -3 then
-3x = 2y - 5
3x-y=5
0+y=5
y=5
to find x substitute y in to the first eqn
x=2×5-5
x=5
Answer:
The radius is 6 1/6
Step-by-step explanation:
The radius is half of the diameter and 12 1/3 divided by 2 = 6 1/6
