Question

The volume of a cuboid is 130cm square. If the solid is 7cm long and 5cm wide, calculate the height

Answer 1

Desola

Answer 2

first, volume is cm^3, not cm^2
7*5*h = 130
h = 130/35 = 26/7
hmmm. Maybe you meant the area is 130 cm^2. In that case,
2(7*5 + 7h + 5h) = 130
35 + 12h = 65
h = 30/12 = 5/2
