Question

Wyraź w litrach i mililitrach objętość prostopadłościanów o wymiarach:
a) 4dm x 2,5dm x 3dm
b) 50cm x 30cm x 80cm
c) 3,5dm x 85cm x 40cm
d) 1m x 1m x 1m

Answer 1

V=a*b*c
a)
V=4*2,5*3=30 dm3 = 30 l = 30 l *1000 ml/l = 30000 ml
b)
50cm=5dm, 30cm=3dm, 80cm=8dm
V = 5*3*8=120 dm3 = 120 l = 120 l *1000 ml/l = 120000 ml
c)
85cm=8,5dm, 40cm=4dm
V = 3,5*8,5*4= 119 dm3 = 119 l = 119 l *1000 ml/l = 119000 ml
d)
1m=10dm
V = 10*10*10 = 1000dm3 = 1000 l = 1000 l *1000 ml/l = 1000000 ml
