Question

Carrie drew a scaled drawing of her fish tank below.

If her fish tank is similar to Pete’s, which of the following could represent a scaled drawing of Pete’s fish tank?

Answer 1

Answer is the last one, 6 x 15 x 5

Reason

Pre image is 12 x 30 x 10

Choices are

❌6 x 30 x 5, side of 30 is the same not scaled

❌15 x 30 x 10, side of 30 is the same not scaled

❌12 x 4, it is not a 3 dimensional figure

✅6 x 15 x 5 is correct, take image divided by pre image for scale, 6/12 = 1/2.

The scale is 1/2 so if you multiplied the pre image sides by 1/2 you will get the image sides

12 x 1/2 = 6
30 x 1/2 = 15
10 x 1/2 = 5

So this is correct
