Prime factorization of 24= 1,24,2,12,3,8,4,6,
3f + 2g = 30 . . .(1)
f + 2g = 26 . . . .(2)
(1) - (2) => 2f = 4 => f = 4/2 = 2
From (2), 2 + 2g = 26 => 2g = 26 - 2 = 24 => g = 24/2 = 12
Therefore, f = 2 and g = 12
Thats easy its 7/6 hope this helps
I believe that the answer is 1845
the surface area of the cube is 1350
the surface area of the pyramid is 495
the total surface area is :

good luck
