How to find the surface area of a rectangular solid

Answer 1

Explanation:

• how to find the surface area of a rectangular solid

The area of ​​the rectangular solid (parallelepiped) is calculated by adding the lateral area and twice the base area: Stot=Slat+2Sb; the area of ​​the rectangular parallelepiped is given by the sum of the areas of the six rectangles that make up its surface, ie Stot=2(ab+ah+bh).

Answer 2

Surface Area = 2 * (length * width + length * height + width * height)

Explanation:

To find the surface area of a rectangular solid (also known as a rectangular prism), you need to calculate the areas of its six faces and then add them together. The formula for the surface area of a rectangular solid is:

Surface Area = 2 * (length * width + length * height + width * height)

Here are the steps to find the surface area:

Identify the length, width, and height of the rectangular solid.

Multiply the length by the width to find the area of the top and bottom faces.

Multiply the length by the height to find the area of the front and back faces.

Multiply the width by the height to find the area of the left and right faces.

Add up all the areas calculated in steps 2, 3, and 4.

Multiply the sum by 2 to account for the two identical sets of faces.

The result will be the surface area of the rectangular solid.

It's important to note that all measurements should be in the same unit (e.g., centimeters, inches) for accurate results.
