Make a cuboid frame with 96cm iron wire. The ratio of length to width is 3:2:1. What's the volume of the cuboid?

Make a cuboid frame with 96cm iron wire. The ratio of length to width is 3:2:1. What's the volume of the cuboid?

3 + 2 + 1 = 6 (parts), 96 ／ 4 × 36 = 12 (CM), 96 ／ 4 × 26 = 8 (CM), 96 ／ 4 × 16 = 4 (CM), 12 × 8 × 4 = 384 (CC); answer: the volume of this cuboid is 384 CC; the volume of this cuboid is 384 CC

Make a cuboid frame with 180 cm long iron wire. The ratio of length, width and height is 4:3:2. What's the volume of the cuboid frame?

Length + width + height = 180 / 4 = 45
Length = 45 * 4 / (4 + 3 + 2) = 5 * 4 = 20
Width = 45 * 3 / (4 + 3 + 2) = 15
Height = 45 * 2 / (4 + 3 + 2) = 10
Volume = l · w · H = 20 * 15 * 10 = 3000 CC

A wire is 48 cm long. Use it to make a rectangular frame with the ratio of length to width to height of 4:3:5. What's the volume of this rectangle

Hello
48÷4=12cm
Length 12 ÷ (4 + 3 + 5) X4 = 4cm
Width 4x3 / 4 = 3cm
Height 4x5 / 4 = 5cm
Volume 4x3x5 = 60 CC
