Homework Help: math

A male moose is 2.6 m tall and 3.2 m long, with antlers that are 1.2 m across.
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?

change 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
