Example 9 A godown is in the form of a cuboid of measures 60 m ร— 40 m ร— 30 m. How many cuboidal boxes can be stored in it if the volume of one box is 0.8 ๐‘š^3 ? Given, Length of godown = l = 60 m Breadth of godown = b = 40 m & Height of godown = h = 30 m Also, a cuboidal box is to be stored in godown Volume of cuboidal box = 0.8 m3 So, Number of boxes = (๐‘‰๐‘œ๐‘™๐‘ข๐‘š๐‘’ ๐‘œ๐‘“ ๐‘”๐‘œ๐‘‘๐‘œ๐‘ค๐‘›)/(๐‘‰๐‘œ๐‘™๐‘ข๐‘š๐‘’ ๐‘œ๐‘“ 1 ๐‘๐‘œ๐‘ฅ) Volume of godown Volume = ๐‘™ร—๐‘ร—โ„Ž = 60 ร— 40 ร— 30 = 6 ร— 4 ร— 3 ร— 1000 = 72000 m3 Now, Number of boxes = (๐‘‰๐‘œ๐‘™๐‘ข๐‘š๐‘’ ๐‘œ๐‘“ ๐‘”๐‘œ๐‘‘๐‘œ๐‘ค๐‘›)/(๐‘‰๐‘œ๐‘™๐‘ข๐‘š๐‘’ ๐‘œ๐‘“ 1 ๐‘๐‘œ๐‘ฅ) = 72000/0.8 = 72000/(8/10) = (72000 ร— 10)/8 = 90,000 โˆด 90,000 cuboidal boxes can be stored in the godown.
