There are ___ square faces on the surface of the figure. Each square face has an area of ___ cm². So, the area of all the visible square faces is ___ cm².
There are ___ non-square rectangles on the surface of the figure. Each rectangle has an area of ___ cm². So, the surface area of all the visible non-square rectangles is ___ cm².
The surface area of the figure is ___ cm².
To answer your questions, let’s break down the information step by step.
1. Square Faces: We need to identify how many square faces the figure has. For instance, if it’s a cube, there are 6 square faces. If each face has an area of ___ cm², you can calculate the total visible area of square faces by multiplying the number of faces by the area of one face.
Example:
– If there are 6 square faces and each has an area of 4 cm², then the total area of the square faces is 6 x 4 cm² = 24 cm².
2. Non-Square Rectangles: Next, determine how many non-square rectangular faces are present and their areas. For example, if there are two rectangular faces, and each area is ___ cm², then you calculate the total area of non-square rectangles similarly.
Example:
– If there are 2 non-square rectangles, each with an area of 8 cm², the total area would be 2 x 8 cm² = 16 cm².
3. Total Surface Area: Finally, to find the total surface area of the figure, add the total visible areas of the square faces and the non-square rectangles together.
Example:
– Using the previous examples, total surface area = Area of square faces + Area of non-square rectangles = 24 cm² + 16 cm² = 40 cm²
