To find the volume of a rectangular parallelepiped if its length for 10% and width 20% more heights and the sum of lengths of all edges is equal to 528 cm.

Length is equal x +0.1kh width x +0.2kh height x 4 (x +0.1kh) +4 (x +0.2kh) the +4th =528 of the 4th +0.4kh the +4th +0.8kh the +4th =528 13.2kh =528 x =40 cm Height is equal to 40 cm length is equal to 40+0.1*40=44 cm width is equal to 40+0.2*40=48 cm Volume cm³ V=a*b*c=40*44*48=84480 is equal
