Question

The total surface area of a box of length 8cm and breadth 6cm is 208 square cm. Find the height of the box ?

Answer 1

Total surface area of the box

= 2[(lb) + (bh) + (lh)]

208 cm2 = 2[(86) + 6 h + 8h]

208 cm2 = 2[48+14 h]

208 cm2 = 96+28 h

208 - 96 = 28 h

112 = 28 h

h = 4

Height=4 cm
