With a 56 cm long wire just welded into a 6 cm long, 5 cm wide, several cm high cuboid
Height = 56 △ 4-6-5 = 3 (CM)
A 56 cm long wire is welded into a cuboid with a length width height ratio of 4:2:1. What is the volume of the cuboid?
Length + width + height = 56 △ 4 = 14 (CM)
4+2+1=7
Length = 14 × 4 / 7 = 8 (CM)
Width = 14 × 2 / 7 = 4 (CM)
Height = 14 × 1 / 7 = 2 (CM)
Volume = 8 × 4 × 2 = 64 (CC)
With a 56cm long wire, it can be welded into a 7cm long, 4cm wide and () cm high rectangular teaching aid
A. 2B. 3C. 4D. 5
56 △ 4 - (7 + 4), = 14-11, = 3 (CM); answer: the height is 3 cm
