Lizzy uses 12 cans of paint a day for a week and 3 days. Each can holds 3 liters and 4 ounces. She had 4 jobs. How much paint did she use

A week is 7 days.

7 days + 3 days = 10 total days.

12 cans per day x 10 days = 120 total cans.

120 cans x 3 liters and 4 ounces = 360 liters and 480 ounces.

480 ounces = 14.195 liters.

360 + 14.195 = 374.195 liters total paint. ( 374 liters and 6.7 ounces)

Round the answer as needed.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
