Answer:
Since there are 2 sides, a front & back, and a top & bottom, you must find the surface area of each of those 3 surfaces and multiply by 2.
Step-by-step explanation:
The formula would be:
Top & Bottom - 5 × 4 (multiply by 2 for top AND bottom)
Front & Back - 5 × 7 (multiply by 2 for front AND back)
Sides - 4 × 7 (multiply by 2 for BOTH sides)
___________________________________________________
Once you find the 3 surface areas, add the areas all together for the total. (I did not show the answer because that is for you to do on your own.)
Ex. Top & Bottom + Front & Back + Sides

Hey there!!
Let us take the number as ' x '
20% of x
= (20/100) × ( x )
= ( 1/5 ) × ( x )
= x/5
The number is decreased by 20% of itself
x - x/5 = 56
5x - x / 5 = 56
4x/5 = 56
Multiplying by 5 on both sides
5x = 56 × 5
5x = 280
dividing by 5 on both sides
4x / 4 = 280 / 4
x = 70
The number is 70
