Answer:
203 square inches.
Step-by-step explanation:
First you have to find the area of the triangles, and you do so by using the formula A = (B·H)/2, where the a represents area, b represents base, and h represents height. Assuming all of the triangles are the same, you multiply 7 by 11 and then divide by 2 (which equals 38.5) and then multiply that by 4 (which equals 154) and then you have the area of all four triangles combined. Then to find the area of the cube you simply square 7, which results in 49, and then add that to the area of the triangles, which leaves you at 203. 203 square inches is your answer.
Your equation is: 5h + 4 = 10h + 8
First subtract 5h from both sides:(So that variable terms stays in one side only)
=> 5h + 4 -5h = 10h + 8 -5h
=> 4 = 5h + 8
Now subtract 8 from both sides:(So constant term stays in the opposite side of variable terms)
=> 4 - 8 = 5h + 8 - 8
=> -4 = 5h
Now divide both sides by 5:(division by coefficient of variable)
=> -4/5 = 5h/5
=> -4/5 = h
=> h = -4/5 = -0.8
