To find the surface area of a figure formed by the net with 2cm, 3cm, and 4cm edges, we need to first identify the shape of the figure.
The net with 2cm, 3cm, and 4cm edges forms a triangular prism.
To find the surface area of a triangular prism, we need to calculate the area of each face of the prism and then add them together.
The triangular faces of the prism can be calculated by using the formula for the area of a triangle:
Area of a triangle = 1/2 * base * height
For the triangular faces with base 2cm and height 3cm, the area is:
1/2 * 2cm * 3cm = 3 square cm
There are 2 triangular faces in the prism, so the total area of the triangular faces is 6 square cm.
Next, we need to calculate the area of the rectangular face of the prism.
The area of the rectangular face with length 2cm and width 4cm is:
2cm * 4cm = 8 square cm
Therefore, the total surface area of the triangular prism is:
6 square cm (triangular faces) + 8 square cm (rectangular face) = 14 square cm
So, the surface area of the figure formed by the net with 2cm, 3cm, and 4cm edges is 14 square cm.
find the surface area of a figure formed by the net with 2cm 3cm and 4 cm edges.
