Answer: [tex]158cm^2[/tex]
Step-by-step explanation:
You can use the following formula to calculate the surface area of the right rectangular prism:
[tex]SA = 2(wl +lh + hw)[/tex]
Where "w" is the width, "l" is the length, and "h" is the height.
Knowing that this rigth rectangular prism has a length of 8 centimeters, a width of 3 centimeters and a height of 5 centimeters, you can substitute these values into the formula.
Then, the surface of the right rectangular prism is:
[tex]SA = 2[(3cm*8cm) + (8cm*5cm) + (5cm*3cm)]\\\\SA=158cm^2[/tex]
Answer:
Surface area of prism = 158 cm²
Step-by-step explanation:
Points to remember
Surface area of rectangular prism = 2(lb + lh + bh)
Where l - Length, b - Breadth and h - Height
To find the surface area of prism
Here l = 8 cm, b = 3 cm and h = 5 cm
Surface area = 2(lb + lh + bh)
= 2[(8*3) + (8 * 5) + (3 *5)]
= 2[24 + 40 + 15]
= 2 * 79
=158 cm²
Surface area of prism = 158 cm²
