प्रश्न
A model of cargo tuck is made to a scale of 1:40. The length of the model is 15cm. Calculate: The volume of the model if the volume of the truck is 6m3
उत्तर
Scale = 1:40
Volume of the truck = 64m3
`"volume(model)"/"volume(truck)"` = Scale
`"volume(model)"/(64 xx (100)^3) = (1)/(40)^3`
Volume(model) = `(64000000)/(64000)`
Volume(model) = 1000cm3.
