can you check my work just to see i'm right.
A yardstick measures 1/4 by 3 by 36 inches. How many yard sticks will fit in a box 3 inches wide and 36 inches high, if the girth of the box is 30 inches?
Girth = 30 inches Girth =3 + 3 + x + x 30 = 6 +2x 2x=30-6=24 x=12 yardsticks are 1/4 in thick 12/.25=48 48 yardsticks could be packed in that box. I'm I right ? If you can check my work...
27 yard sticks, not sure though If the box is 3 in wide and its girth is 30 in then its depth must be 12in. 1/4in thick means you'll fit 12 into 3in 3in wide means you'll get 4 in 12in so number of rulers = 12x4=48 A yardstick measures 1/4 by 3 by 36 inches.

@Esmy wait a moment lol
calculate volume of one yardstick and volume of box so number of yardsticks is volume of box divided by volume of each yardstick
try calculating from my method and match answers :P ..
volume of stick = 1/4 * 3 * 36 = 27 cubic inches .. right ?
volume of box = 3 * 30 * 36 = 3240.. ok ?
so total yardsticks are 3240/27 = 120.. okay ? Unfortunately your answer was wrong. D:
OH I GET IT yeah yeah the width of the yardstick fits the 3 inch width of the box and The 36 inch length of the yardstick fits the height and 4 of the 1/4 inch yardsticks make a stack 1 inch high The number of 1/4 inch thick yardsticks that can be stacked up in 30 inches is 4 * 30 = 120
I got that at first but I didn't think it was the answer... :/
