Answer 2

Answer:

I take toothpaste

(i) length = 14 cm , breadth = 3 cm , height = 2.4 cm

(ii) Curved surface area of the toothpaste = 2h(l+b)

= 2 × 2.4( 14 + 3 )

= 4.8(17)

= 81.6 cm²

total surface area of toothpaste = 2(lb + lh + bh)

= 2( 14 × 3 + 14 × 2.4 + 3 × 2.4)

= 2( 42 + 33.6 + 7.2 )

= 2( 82.8 )

= 165.6 cm²

Volume of toothpaste = l × b × h

= 14 × 3 × 2.4

= 100.8 cm³
