Triangular faces:
Area = (1/2) x 4ft x 4.75ft = 9.5 sq ft each
Total area for both triangular faces = 2 x 9.5 sq ft = 19 sq ft
Rectangular faces:
Area = 4ft x 8ft = 32 sq ft (for one face)
Area = 4ft x 5ft = 20 sq ft (for one face)
Area = 8ft x 5ft = 40 sq ft (for one face)
Total area for all three rectangular faces = 32 sq ft + 20 sq ft + 40 sq ft = 92 sq ft
4 Add the areas of all faces to find the total surface area:
Total surface area = 19 sq ft (triangular faces) + 92 sq ft (rectangular faces) = 111 sq ft
Therefore, the total surface area of the tent is 111 square feet.
The total surface area of the tent can be determined by calculating the areas of the triangular and rectangular faces and summing them up
1 Identify the faces of the triangular prism:
Two triangular faces with base 4ft, height 4.75ft, and one side 5ft.
Three rectangular faces with dimensions 4ft x 8ft, 4ft x 5ft, and 8ft x 5ft.
2 Calculate the area of each face:
Triangular faces: (1/2) x base x height.
Rectangular faces: Length x Width.
3 Add the areas of all faces to find the total surface area
