Question

9.
If l=25 cm, b= 20 cm and h= 15 cm find TSA & volume of given cuboid.

Answer 1

Answer:

Volume of cuboid =l*b*h

= 25*20*15

=7500

Answer 2

Answer:

TSA = 2350 m²

Volume = 7500 m³

Step-by-step explanation:

TSA = 2(lb+bh+lh)

= 2{(25×20)+(20×15)+(25×15)}

= 2(500+300+375)

= 2×1175

= 2350 m²

Volume = lbh

= 25×20×15

= 7500 m³
