pencil holder shaped like a triangular prism is shown the height of the prism is 12 CM what is the lateral surface area of the pencil holder and square centimeters 10cm 12cm 7cm 7cm
To find the lateral surface area of the triangular prism, we need to find the perimeter of the triangular base and multiply it by the height of the prism.
The triangular base of the pencil holder has sides measuring 10cm, 12cm, and 7cm.
The perimeter of the triangular base would be the sum of these sides: 10cm + 12cm + 7cm = 29cm.
So, the lateral surface area of the pencil holder would be 29cm * 12cm = 348 square centimeters.
