Question

Find the surface area of the figure shown.

Answer 1

Answer:

The correct answer is option d.  576 ft^2

Step-by-step explanation:

From the figure we can see that a prism

To find the surface area

Surface area = Base area + area of 2 triangles + Two side area

Base area = length * breadth = 15 * 12 = 180 ft^2

Area of triangle = bh/2 = (12 * 8)/2 = 48 ft^2

Area of two triangle = 48 * 2 = 96 ft^2

Area of one side = 15 * 10 = 150 ft^2

Area of two side = 2 * 150 = 300 ft^2

Surface area = 180 + 96 + 300 = 576 ft^2

The correct answer is option d.  576 ft^2
