Answer:
120 cm squared
Step-by-step explanation:
1.the bases in this case are in blue,these are not included in lateral surface area.
first we must find the area of the top & bottom squares.
(4x4=16)
Then the side rectangles
(11x4=44)
then We add,there are two squares and two rectangles included in the lateral surface area.So we can do 16x2=32 and 44x2=88.
now that we have all our measurements we can add these numbers
88+32=120 cm squared
You can use scale to solve. 5185/8.5=610
4845/610= about 8 hours.
W = 6
L = 36
2L + 2W = 84
L = 6W
Substitute for L in the first equation
2 (6W) + 2W = 84
12W + 2W = 84
14W = 84
Substitute W in the first equation
2L + 2(6) = 84
2L + 12 = 84
2L = 72
Plug both values in both equations to be sure
2(36) + 2(6) = 84
36 = 6 * 6
Hope that helps!
