The base of pyramid a is a rectangle with a length of 10 meters and a width of 20 meters. the base of pyramid b is a square with 10-meter sides. the heights of the pyramids are the same.
the volume of pyramid a is the volume of pyramid b. if the height of pyramid b increases to twice that of pyramid a, the new volume of pyramid b is the volume of pyramid a.
answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.
p = perimeter
l = length
p = 2l + 2x
p = 2(l+x) < ==== perimeter of the base of the box.
well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
