Answer is 45 (33-28+40=45)
It would be 20 because if you estimate 53 you would get 50 so 50÷3 would be clase to 2 and then add 1 zero and you will get 20 so 20 is your answer. Hope this helped. ☺
6 feet = 72 inches
1 inch = 2.54 centimeters
72 * 2.54 = 182.88 cm which equals
1.8288 meters
Note: Consider x be the breadth of the box.
Given:
The surface area of the box is 204.25 square feet.
Length of the box = 10 ft
Breadth of the box = x ft
Height of the box = 6.5 ft
To find:
The value of x.
Solution:
The surface area of a cuboid is:

Where, l is length, b is breadth and h is height of the cuboid.
Putting
in the above formula, we get



Using distributive property, we get




Divide both sides by 33.


Therefore, the correct option is B.
