I need help with this ... I don't get it

1. The volume is comprise of a cube and prism
V = ( x + 2) ( 2x + 4) + ( x + 2)^2
Solve for x
X = 10.12
2. 1050 = (2x – 4) ( 3x) 5
1050 = (2x – 4) 15x
1050 = 30x^2 – 60x
Solve for x
X = 7
3. 148 = ( x – 5) ( x – 6 ) ( x – 4)
Solve for x
X = 10.35
4. 144pi = pix^2(21)
X = 2.62
