What you are calling a cuboid is what was called a rectangular prism when I went to school. It has width W, length L and height H. See

Total surface area is

2(WL+ WH + HL) = 40

Lateral surface area (4 sides) is:

2(WH + HL) = 26

Therefore (Top + Base area) =

2 WL = 14, and so

WL = base area = 7 cm^2
