Final answer:
To determine the volume of a cuboid with a length of 4cm, a width of 5cm, and a height that is 3cm longer than the width, you calculate using the formula Volume = Length × Width × Height. After computing, you find that the volume of the cuboid is 160 cubic centimeters (cm³).
Step-by-step explanation:
To find the volume of a cuboid, you simply multiply the length, width, and height of the cuboid. The student provides the cuboid's length as 4cm and width as 5cm, and states that the height is 3cm longer than the width. Therefore, the height is 5cm + 3cm, which equals 8cm.
Now, we can calculate the volume using the formula:
Volume = Length × Width × Height.
When we substitute the given dimensions into the formula we get:
Volume = 4cm × 5cm × 8cm, which equals 160 cubic centimeters (cm³).
So, the volume of the cuboid is 160 cm³.
