How to Find the Surface Area of a Rectangular Prism?
The surface area of a rectangular prism is the number of unit squares that can be fit into it and it is measured in square units. The surface area of a rectangular prism whose length 'l', breadth 'b', and height 'h' are calculated by the following formula:
The surface area of a rectangular prism = 2(lb + bh + lh)
Solved Examples on Surface Area of a Rectangular Prism Calculator
Example 1:
Find the surface area of a rectangular prism whose length (l) = 8 units, breadth (b) = 5 units, and height (h) = 7 units?
Solution:
The surface area of the rectangular prism = 2(lb + bh + lh)
= 2( 8 × 5 + 5 × 7 + 8 × 7)
= 2(40 +35 + 56)
= 2 × 131
= 262 square units.
Example 2:
Find the surface area of a rectangular prism whose length (l) = 4 units, breadth (b) = 5 units, and height (h) = 6 units?
Solution:
The surface area of the rectangular prism = 2(lb + bh + lh)
= 2(4 × 5 + 5 × 6 + 4 × 6)
= 2(20 + 30 + 24)
= 2 × 74
= 148 square units.
Example 3:
Find the surface area of a rectangular prism whose length (l) = 3 units, breadth (b) = 7 units, and height (h) = 9 units?
Solution:
The surface area of the rectangular prism = 2(lb + bh + lh)
= 2(3 × 7 + 7 × 9 + 3 × 9)
= 2(21 + 63 + 27)
= 2 × 111
= 222 square units.
Similarly, you can try the surface area of a rectangular prism calculator to determine the surface area of a rectangular prism with the following dimensions:
1) length (l) = 16 units, breadth (b) = 5 units, and height (h) = 7 units
