Tina is planning to paint a wood box she is using small paint cans that cover 20 square feet of surface area how many cans will Tina need to paint the outside of her wood box

How much is the ouside of the box?

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to
