Let’s draw a plan of your classroom using your feet and your hands applying the suitable scale to draw it
1 foot: 20cm 1 hand: 10cm
31 feet are equivalent to 620cm 24 feet are equivalent to 480cm 4,5 hands = 45cm 3,5 hands=35cm Therefore we have 2.3 Drafting scale 4hands x 18cm/hand= 72cm 3hands x 18cm/hand= 54cm 31 feet x 20cm/foot= 620cm 24 feet x 20cm/foot=480cm
2.3 Drafting scale Which scale could we use to draw the classroom and your desks on your notebooks? 54cm 72cm Desk 480cm 620cm Classroom width length
2.3 Drafting scale Let’s use the 1:100 scale , so the drawing will be 100 times smaller than reality 480 4,8 wide 620 100 Real 6,2 1 Drawn Long Classroom 54 0,54 wide 72 100 Real 0,72 1 Drawn Long Desks
