The surface area of the solid above is B. 126 cm2. Therefore , B. 126 cm2[s correct .
The solid is a rectangular prism.
To find the surface area, we need to find the areas of all six faces and add them up.
The two largest faces have dimensions 5 cm x 6 cm.
Their areas are: 2 * 5 cm * 6 cm = 60 cm2
The two next largest faces have dimensions 3 cm x 6 cm.
Their areas are: 2 * 3 cm * 6 cm = 36 cm2
The two smallest faces have dimensions 3 cm x 5 cm.
Their areas are: 2 * 3 cm * 5 cm = 30 cm2
Adding up the areas of all six faces, we get the total surface area:
60 cm2 + 36 cm2 + 30 cm2 = 126 cm2
Therefore, the answer is B. 126 cm2.
Here is a detailed explanation of the steps involved in solving the problem:
Identify the geometrical shape of the solid. In this case, the solid is a rectangular prism.
List the dimensions of the solid. The dimensions are 5 cm, 6 cm, and 3 cm.
Find the areas of all six faces of the solid. To do this, we use the following formula:
Area = length * width
Add up the areas of all six faces to find the total surface area.
Total surface area = sum of the areas of all six faces
