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
