What is the surface area of a rectangular prism measuring 3 1/2 ft.by 2 3/8 ft. by 8 feet ?

I'll be glad to check your answer.

Thank you so much!

To find the surface area of a rectangular prism, we need to calculate the area of each of its six faces and then sum them up.

The rectangular prism given has three dimensions:
Length = 3 1/2 ft = 3.5 ft
Width = 2 3/8 ft = 2.375 ft
Height = 8 ft

To calculate the surface area, we need to find the area of each face.

1. Face 1 (Top and bottom): The area of the top and bottom faces is the same since they are congruent.
Area = Length × Width

Area1 = 3.5 ft × 2.375 ft

2. Face 2 (Front and back): The area of the front and back faces is also the same.
Area2 = Length × Height

Area2 = 3.5 ft × 8 ft

3. Face 3 (Sides): The area of the two side faces is also the same.
Area3 = Width × Height

Area3 = 2.375 ft × 8 ft

Now, we can calculate the area of each face and sum them up to find the total surface area.

Total Surface Area = 2 × (Area1 + Area2 + Area3)

Once the numerical values are substituted into the equation, the calculation can be done to find the final answer.
