Question

The length and breadth of a box are 90cm and 60cm respectively. If its surface area is 2.28m². find its height​

Answer 1

Answer:

Step-by-step explanation:

Total surface area = 2( lb +bh +hl)

228*100/100 = 2(90*60 +60*

h+ 90*h)

228= 2(5400+60h +90h)

228 /2= 5400 + 150h

114-5400 /150 = h

- 5339.24 =h

Therefore height of box is + 5339.24
