Calculate the total surface area if the rectengular prism with lengh=7,2m breadth=5m and lengh=3.32m . Give the answer correct to 2 decimal places
I haven't got the answer
total surface area
= 2(7.2)(5) + 2(7.2)(3.32) + 2(5)(3.32)
why are you using both a "," and a "." to represent the decimal place?
To calculate the total surface area of a rectangular prism, you need to find the area of each of the six faces and then add them together.
The formula to find the surface area of a rectangular prism is:
Surface Area = 2(length x breadth + breadth x height + height x length)
Given the dimensions:
Length = 7.2m
Breadth = 5m
Height = 3.32m
Let's calculate the surface area step by step:
1) Calculate the area of the first face (length x breadth):
Area 1 = 7.2m x 5m
2) Calculate the area of the second face (breadth x height):
Area 2 = 5m x 3.32m
3) Calculate the area of the third face (height x length):
Area 3 = 3.32m x 7.2m
4) Add all the areas together and multiply by 2:
Surface Area = 2(Area 1 + Area 2 + Area 3)
Plug in the values and calculate the surface area:
Area 1 = 7.2m x 5m = 36m²
Area 2 = 5m x 3.32m = 16.6m²
Area 3 = 3.32m x 7.2m = 23.904m²
Surface Area = 2(36m² + 16.6m² + 23.904m²)
Surface Area = 2(36m² + 16.6m² + 23.904m²)
Surface Area = 2(76.504m²)
Surface Area = 153.008m²
Thus, the total surface area of the rectangular prism is 153.008 square meters.
