Aright rectangular prism has a length of 8 centimeters, a width of 3 centimeters, and a height of 5 centimeters. what is the surface area of the prism? enter your answer in the box. cm²

Step-by-step explanation:

You can use the following formula to calculate the surface area of the right rectangular prism:

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:

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
