Answer:
246 Square Feet
Step-by-step explanation:
The cubes are of side length 1ft , 2ft, 3ft , 4ft, and 5ft in that order.
If the side of each smaller cube is completely touching the side of the adjacent larger cube.
- In the first and last cubes, 5 sides out of 6 are visible, so we use the formula for their surface area.
- In the 2nd, 3rd and 4th cubes, only 4 sides out of 6 are visible, so we use the formula for their surface area.
Surface Area of the Solid
are the length of the cubes in that order
Surface Area of the Solid
The perimeter of a rectangle is given by the following formula: P = 2W + 2L
To solve this formula for W, the goal is to isolate this variable to one side of the equation such that the width of the rectangle (W) can be solved when given its perimeter (P) and length (L).
P = 2W + 2L
subtract 2L from both sides of the equation
P - 2L = 2W + 2L - 2L
P - 2L = 2W
divide both sides of the equation by 2
(P - 2L)/2 = (2W)/2
(P - 2L)/2 = (2/2)W
(P - 2L)/2 = (1)W
(P - 2L)/2 = W
Thus, given that the perimeter (P) of a rectangle is defined by P = 2W + 2L ,
then its width (W) is given by W = (P - 2L)/2
Answer:
j=38
Step-by-step explanation:
j/-2+7=-12
Subtract 7 from each side
j/-2 +7-7 = -12 -7
j/-2 = -19
Multiply by -2 to isolate j
j/-2 * -2 = -19*-2
j = 38
Answer:
