Answer:
<h2>652 ft²</h2>
Step-by-step explanation:
Look at the picture.
It's a net of right rectangular prism.
We have three pairs of rectangles:
7ft × 8ft
7ft × 18ft
8ft × 18ft
The formula of an area of a rectangle l × w:
A = lw
Calculate the areas:
A₁ = (7)(8) = 56 ft²
A₂ = (7)(18) = 126 ft²
A₃ = (8)(18) = 144 ft²
The Surface Area :
S.A. = 2A₁ + 2A₂ + 2A₃
Substitute:
S.A. = 2(56) + 2(126) + 2(144) = 652 ft²

Answer:
There are 3 prime numbers shown on the die: 2, 3 and 5. The probability of showing a prime number on a single die is 1/2, hence the probability of not showing a prime number is also 1/2. Total possible outcomes when two dice are rolled = 6*6 = 36. Total possible outcomes when two dice are rolled = 6*6 = 36.
