Give the name of the following nets of solid figures.
Cube

Cuboid

Square Pyramid

Triangular Prism

Cylinder

Cone

Worksheet Number 25 Solid Figure and its nets

VOLUME OF THE SOLID FIGURE

Volume – the amount of space occupying the solid figure.
Volume of cuboid Formula: V =(Length)(Width)(Height) = LWH cuboid

Example 1. Calculate the volume of the cuboid below.
3 cm 4cm 6 cm

Solution: V = LWH = (6cm)(4cm)(3cm) = 72 cubic centimeters V = 72 cm
cuboid Solution: V = LWH = (6cm)(4cm)(3cm) = 72 cubic centimeters V = 72 cm 3 cuboid

2. A bottle contains 1,500 cubic centimeters
2. A bottle contains 1,500 cubic centimeters. The water is poured into a hollow cuboid with a length of 15 cm, a width of 12 cm, and a height of 8 cm. Find the volume of the water remaining in the bottle.

cuboid cuboid Solution: Volume of water remaining in the bottle = Water on the bottle - V V = LWH = (15cm)(12cm)(8cm) = 1,440 cm Volume of water remaining in the bottle = 1,500 cm – 1,440 cm = 60 cm 3 3 3 3
