Question

A small indoor greenhouse is made entirely of glass planes held together with tape. It is 30 cmlong , 25 cm wide and 25 cm high.
1) What is the area of the glass ?
2) How much of tape is needed for all the 12 edges ?

Answer 1

Solution:-
Given  L = 30 cm, B = 25 cm and H = 25 cm
Total surface area of the greenhouse = 2(LB + BH + HL)
= 2(30*25 + 25*25 + 25*30)
= 2(750 + 625 + 750)
= 2*2125
Total surface area of the greenhouse = 4250 sq cm
Length of the tape required for the 12 edges = 4(30 + 25 + 25)
= 4*80
Length of the tape required = 320 cm
