In redesigning a cold storage, the length is increased by 30% , the breadth is increased by 50% and the height is reduced by 20%. what is the net increase in the volume of the redesigned cold storage compared to the previous design?

Question

Accepted Answer

56% (ব্যাখ্যা: Let, length, width and height of the cold storage are respectively l, w and h. so, volume = lwh New length = l + 30/100 l = 1.3 l New width = w + 50/100 w = 1.5 w New height = h - 20/100 h = 0.8 h so, new volume = 1.3 l * 1.5w * 0.8 h = 1.56 lwh increase in volume = (1.56 - 1)lwh = 0.56 lwh percentage increase in volume = 0.56 * 100% = 56%.)
