Question

A small indoor greenhouse ( herbarium ) is made entirely of glass panes including base held together with tape. It is 30cm long, 25cm wide and 25cm high. How much of tape is needed for all the 12 edges?

Answer 1

Since length=30, width=25, height=25,
Length of edges=4(l+b+h)
Length of edges=4(30+25+25)
                          =4(80)=320 cm
