This net consists of a square and 4 identical triangles. What is the surface area of the solid this net can form?

144 square inches
184 square inches
224 square inches
264 square inches

3) 224 square inches

Step-by-step explanation:

SA is equal to area of 4 triangles + square. So:

Triangles:

4*1/2*B*h

4*1/2*8*10

2*80

160

Square:

8*8

64

Add them together to get 224 square inches

C, 224 inches squared

Step-by-step explanation:

When formed into a solid, the triangles are folded upwards to make a pyramid. You can find the surface area by finding the areas of the individual shapes.

There are four triangles with a height of 10 inches and a base of 8 inches.

There is one square with a side length of 8 inches.

Triangle area formula : A = (b * h) / 2

Square area formula: A = s^2

(10 * 8) / 2 = 40

8 ^ 2 = 64

There are four triangles with area of 40 and one square with area of 64.

40 + 40 + 40 + 40 + 64 = 224 inches squared. The correct answer choice is C.

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
