05.07) The net of a pyramid is shown below: The net of a square based pyramid, with bases labeled 7 inches and the height of the triangle labeled 14 inches. The surface area of the solid is ____ square inches. Numerical Answers Expected!

Accepted Solution

A:
Answer: 245 [tex]in^{2}[/tex]Step-by-step explanation:You can find the Surface Area of a figure by adding up the areas of each shape.First you have to find the area of the base.7Γ—7 = 49Then you can find the area of the 4 triangles that complete the pyramid.Formula for area of a triangle: [tex]\frac{1}{2} bh[/tex] (one half of base times height)[tex]\frac{1}{2} (14*7) = x\\\frac{1}{2} 98 = x\\x = 49[/tex]Since all the triangles are the same, you only have to calculate that once.Now you just add everything together, and that's your surface area.[tex]49+49+49+49+49= 245[/tex]Please mark brainly if it helped you out!~
