Answer:
You can use the formula for the volume of a cuboid, which is Volume = length x width x height
You are given the volume of the cuboid as 108cm^3, the length as 4cm, and the width as 9cm. Let's substitute these values into the formula and solve for the height:
108cm^3 = 4cm x 9cm x height
To solve for height, you can divide both sides by 36 (which is equal to 4cm x 9cm) to isolate height:
108cm^3 ÷ 36 = 4cm x 9cm x height ÷ 36
3cm = height
So the height of the cuboid is 3cm.
