Question

If the internal dimensions of a closed box made up

of wood 1.5m thick are 24m, 18m and 12m, find

the volume of wood in box.​

Answer 1

Answer:

171 cubic meters

Step-by-step explanation:

internal volume = 24×18×12 = 5184 cubic meters

external volume = [24+1.5+1.5][18+1.5+1.5][12+1.5+1.5] { ∵the dimensions are incresed on both the sides}

=[17][21][15] = 5355 cubic meters

the volume of wood used = 5355-5184 = 171 cubic meters

∴ 171 cubic meters of wood is used to make this box
