Answer:
1.8 m
Step-by-step explanation:
the scale drawing of the quartz layer is 2 cm high and 24 cm long.
As sen, the height of layer is 0.15 m
it means, the height 0.15 m is equivalent to 2 cm.
So, 2 cm is equivalent to 0.15 m on scale
1 cm is equivalent to 0.15 / 2 = 0.075 m
On scale length of the quartz layer = 24 cm
Thus, the actual length of the quartz layer = 24 x 0.075 m = 1.8 m
