Question

the roof of a guard house is to be reconstructed from a shed type to a hip roof, calculate the lateral surface area, total surface area and volume if the dimensions are 8ft height and base of 10ft

Answer 1

Answer------

Calculate the area of the wall below the gable by multiplying the width of the wall by the height of the eaves. For example, if the wall is 25 feet wide and the eaves are 20 feet above ground level, the wall has a surface area of 500 square feet: 25 x 20 = 500.

Step 4

Deduct the distance from the ground to the eaves from the distance from the ground to the roof ridge. The result is the height of the gable triangle. For example, if the building is 30 feet high and the eaves are 20 feet above ground level, the gable height is 10 feet: 30 - 20 = 10.
