An artist wants to carve scale models of the moose. She uses a scale factor of 1/30.

a) What are the dimensions of the carvings to the nearest centimetre?

b) How many carvings can she make using part of a railway tie that is 22 cm by 18 cm by 32 cm?

**Reiny**, Monday, January 14, 2013 at 8:56amchange your m to cm (real easy, just multiply by 100), then divide each of those by 30 to get

8.67 by 10.67 by 4

so she must start with a block of that size

32÷(32/3) =3 --- 3 lengths

22÷(26/3) = 2.5 --- not enough for 3 heights

looks like she can only make 2 carvings
