Answer: 108 cm squared
Step-by-step explanation: To find the lateral area, you have to multiply the perimeter of the base by the height of the rectangular prism.
1. Perimeter: 10 + 10 + 8 + 8 = 36
2. Lateral area: 36 * 3 = 108
HOPE THIS HELPED YOU!
To solve for h, you need to isolate/get h by itself in the equation:
s = hp + 2b Subtract 2b on both sides
s - 2b = hp + 2b - 2b
s - 2b = hp Divide p on both sides to get h by itself
3x+22=10x-41
-22 -22
----------------------
3x=10x-63
-10x -10x
-----------------
-7x=-63
divide by -7 on both sides
yep ur right its x=9
Answer: $6.50
If the number is below 5 (so 1-4) you round down. If its above 5 (5-9), you round up.
E.G. 78.89
Round this to the nearest 10th, you'll get 78.90
