Question

Muchia unui vas in forma de cub are lungimea de 8dm.Muchiile unui vas avand forma unui paralelipiped dreptunghic sunt respective de 5,de 4,de 3 ori mai mari decat muchia cubului.Cati litri de apa incapin vasul paralelipipedic

Answer 1

L=5*8=40dm
l=4*8=32dm
h=3*8=24dm
Vp = 40*32*24 = 30720 dm^3 = 30720 litri

Answer 2

8 * 8 * 8 = 512 dm³ = 0,512 m³
8 * 5 = 40 dm
8 * 4 = 32 dm
8 * 3 = 24 dm
40 * 32 * 24 = 30720 dm³ = 30,720 m³
1m³ = 1000 l 
30,720 * 1000 = 30720 l apa
