#### Question

A small indoor greenhouse (herbarium) is made entirely of glass panes (including base) held together with tape. It is 30 cm long, 25 cm wide and 25 cm high. What is the area of the glass?

#### Solution

Length (l) of green house = 30 cm

Breadth (b) of green house = 25 cm

Height (h) of green house = 25 cm

Total surface area of green house

= 2[lb lh + bh]

= [2(30 × 25 + 30 × 25 + 25 × 25)] cm2

= [2(750 + 750 + 625)] cm2

= (2 × 2125) cm2

= 4250 cm2

Therefore, the area of glass is 4250 cm2.

Is there an error in this question or solution?
