Question

The length and breadth and volume of cuboid are 80 CM 60 cm and 19200 cubic CM respectively find its height total surface area and lateral surface area

Answer 1

Step-by-step explanation:

Volume of cuboid=19200cm^3

• lbh=19200
• 80×60×h=19200
• h=19200÷(80×60)
• h=4cm.

LSA of cuboid = 2h(l+b)

• 2×4(80+60)
• 8(140)
• 1120cm^2

TSA = 2(lb+bh+hl)

• 2[(80×60)+(60×4)+(4×80)]
• 2[4800+240+320]
• 2×5360
• 10720cm^2
