PRISM VOLUM V = base area x height 2 . A bath cuboid with lenght 1 m, CUBOID VOLUM width 8 dm V = l.w.h and height 50 cm determine theexamples volum1. A cuboid has measure ( 9 x 6 x 4 ) cm determine the volum

5 cm 8 cm 12 cm

EXAMPLES OF ITEMS1. The Cuboid sketch will be made with wire

with the measure ( 25 x 15 x 10 ) cm. If the lengh of wire is 2.4 m available. Please determine the rest of wire length

2. A tab of wire with the length 5 m , it will be made into a cuboid sketch with the measure

( 12 x 10 x 8 ) cm . a. How many cuboid sketch can be made? b. Determine the rest of wire length . . .
