Answer 2

Step-by-step explanation:

LENGTH OF LAPTOP COVER, L= 45cm = 0.45m

BREADTH OF LAPTOP COVER,B=40 cm = 0.40m

HEIGHT OF LAPTOP COVER,H= 30cm = 0.30m

VOLUME OF THE COVER , V= L.B.H

V = 0.45*0.40*0.30 m³

= 0.054 m³

NOW SINCE A CARDBOARD CONATINS 15 SUCH COVERS

V OF CARDBOARD = 15 * V OF COVER

V= 15 *0.054 m³

V = 0.81 m³
