The formula to calculate the surface area of a rectangular prism is:

Surface Area = 2lw + 2lh + 2wh

Given the numbers:
l = 7
w = 3
h = 5

Substitute the values into the formula and calculate:

Surface Area = 2(7)(3) + 2(7)(5) + 2(3)(5)
Surface Area = 2(21) + 2(35) + 2(15)
Surface Area = 42 + 70 + 30
Surface Area = 142 in.^2

Therefore, the surface area of the rectangular prism with dimensions 7, 3, and 5 is 142 square inches.

Using the same formula for the surface area of a rectangular prism:

Surface Area = 2lw + 2lh + 2wh

Given the numbers:
l = 9
w = 5
h = 8

Substitute the values into the formula and calculate:

Surface Area = 2(9)(5) + 2(9)(8) + 2(5)(8)
Surface Area = 2(45) + 2(72) + 2(40)
Surface Area = 90 + 144 + 80
Surface Area = 314 cm^2

Therefore, the surface area of the rectangular prism with dimensions 9, 5, and 8 is 314 square centimeters.

Using the same formula for the surface area of a rectangular prism:

Surface Area = 2lw + 2lh + 2wh

Given the numbers:
l = 1 mm
w = 5 mm
h = 4.5 mm

Substitute the values into the formula and calculate:

Surface Area = 2(1)(5) + 2(1)(4.5) + 2(5)(4.5)
Surface Area = 2(5) + 2(4.5) + 2(22.5)
Surface Area = 10 + 9 + 45
Surface Area = 64 mm^2

Therefore, the surface area of the rectangular prism with dimensions 1, 5, and 4.5 is 64 square millimeters.

To find the total surface area of a rectangular prism, you can use the formula:

Surface Area = 2lw + 2lh + 2wh

Given the numbers:
l = 4 in
w = 2.25 in
h = 8 in

Substitute the values into the formula and calculate:

Surface Area = 2(4)(2.25) + 2(4)(8) + 2(2.25)(8)
Surface Area = 2(9) + 2(32) + 2(18)
Surface Area = 18 + 64 + 36
Surface Area = 118 in^2

Therefore, the surface area of the rectangular prism with dimensions 4, 2.25, and 8 inches is 118 square inches.
