Volume = l×b×h = 48×40×30 = 57600 cm²
Area of a square = Side × Side
Side = 7x-3
Area of the square = (7x-3) × (7x-3)
= 7x(7x-3) -3(7x-3)
= 49x^2 -21x -21x +9
=49x^2 -42x +9
It would be: -7/12 + 7/10 = -35+42 /60 = 7/60
So, your final answer is 7/60
Hope this helps!
Sixty more than ninety times two multiply by x
Just subtract the smaller volume from the larger:
10 × 10 ×15 - 7 × 9 × 12
First you would multiply 10 × 10 × 15 = 1500 and then multiply 7 × 9 × 12 = 756.
After you would subtract 1500 - 756 which would give you 744
I hope that helped!
