1 litre can of paint covers 11m squared. How many cans of paint would you need to cover a perfectly square ceiling that has a side length of 5.2 m?

If paint caosts $29.95 per can and there is a 12% tax. How much would it cost to paint the ceiling?

Hold it! im going to try this myself but i want someone to check if i did it right:

5.2 x 5.2 = 27.04

11 x 3= 33

You would need 3 cans of paint.

27.04 x 3 = 81.12

ok now im stuck... how do you do this part::If paint caosts $29.95 per can and there is a 12% tax. How much would it cost to paint the ceiling?

5.2 * 5.2 = 27.04 square meters

27.04 / 11 = 2.46 = 3 cans of paint

(3 * 29.95) * 1.12 = ?

OOPS oh so is this how you do it:: 29.95 x 3= 89.85x 1.12 = $100.632

i just have one question: where did the 1.12 come from?

1.12 = 112%

Nope it would be 1.12=12%

if you are going to follow this way

29.95 x 0.12=3.594

so look here 29.95 + 3.594=33.544

29.95 x 1.12 =33.544
