The first number is "a" and the second is "a+1" ( the Numbers are consecutive).
a + (a+1) = 141
2a = 141 - 1
2a = 140
a = 70
The Numbers are 70 and 71
= (5a²)³ - 4³
you can apply the cubic factorisation rule
(a³ - b³) = (a - b)(a² - ab + b²)
= [5a² - 4][ (5a²)² - 20a² + 16]
= [5a² - 4][25a⁴ - 20a² +16]
I think this is it.
hope it helps.

ANSWER :
a. 628 cubic foot
b. 52 cubic foot
c. 1.17 ton
EXPLANATION :
The volume formula of a cylinder is :
The volume formula of a cone is :
From the problem, we have a diameter of 10 ft, so the radius is r = 5 ft
Cylinder's height is 8 ft and cone's height is 2 ft
a. volume of cylinder part :
b. volume of cone part :
c. The combine volume is 628 + 52 = 680 cubic foot
A dry corn weighs 45 lbs per cubic foot.
That will be :
There are 2000 pounds per ton, so that will be :
