Detailed Solution

Dimensions of the cubic shape greenhouse,

length, l = 30 cm,

breadth, b = 25 cm,

height, h = 25 cm

Total surface area of this cubic greenhouse,

TSA = 2 (lb + bh + hl)

TSA = 2 ((30 \times 25) + (25 \times 25) + (25 \times 30))

TSA = 2 (750 + 625 + 750)

TSA = 4250 {cm}^{2}

This is the area of glass.
There are 4 lengths, 4 breadths and 4 heights. Thus, total length of edges,

= 4 (l + b + h)

= 4 (30 + 25 + 25)

= 320 cm

So. correct option is 1.
