# Om te ondersoek en te skat

Module by: Siyavula Uploaders. E-mail the author

## AKTIWITEIT: Om te ondersoek en te skat [LU 1.6.2]

1. Jou opvoeder sal die nodige papier aan jou voorsien. Kyk goed na die diagram hieronder en trek dit dan presies net so oor. Kyk dan of jy jou eie kubus (vierkantige blokkie) kan bou.

• Jy het nou ’n houer met die volgende afmetings:

1 cm by 1 cm by 1 cm

• Daarom sê ons die volume van die houer is:

1 cm × 1 cm × 1 cm = 1 cm3

(een kubieke sentimeter)

volume = lengte × breedte × hoogte

2. Hoeveel van hierdie boksies (van 1 cm3) sal jy nodig hê om ’n kubus van 8 cm3 te bou? (2 cm × 2 cm × 2 cm)

2.1 8 cm3 = (2 cm × 2 cm × 2 cm): ___________________ blokkies

2.2 27 cm3 = (3 cm × 3 cm × 3 cm): __________________ blokkies

2.3 64 cm3 = (4 cm × 4 cm × 4 cm): __________________ blokkies

2.4 125 cm3 = (5 cm × 5 cm × 5 cm): _________________ blokkies
