The total surface area of each prism are:
1) TSA = 2225 ft²
2) TSA = 120 ft²
3) TSA = 198 cm²
4) TSA = 4380 m²
How to find the total surface area of the prism?
To find the total surface area of the prism, we will find the individual areas and sum them up.
Formula for area of a triangle is:
A = ¹/₂ * base * height
Formula for area of a rectangle is:
A = Length * Width
Thus:
1) Total Surface area of prism is:
TSA = 4(¹/₂ * 32 * 25) + (25 * 25)
TSA = 2225 ft²
2) Total Surface area of prism is:
TSA = 4(¹/₂ * 4 * 7) + (4 * 4)
TSA = 120 ft²
3) Total Surface area of prism is:
TSA = 2(¹/₂ * 10 * 7) + 2(¹/₂ * 8 * 6) + (10 * 8)
TSA = 198 cm²
4) Total Surface area of prism is:
TSA = 2(¹/₂ * 60 * 25) + 2(¹/₂ * 30 * 36) + (60 * 30)
TSA = 4380 m²
