Volume of a cuboid: length width height

1
Volume of a cuboid length width height
Length 6 cm
Width 4 cm
Height 2 cm
Volume 6 4 2 48 cm3
2
Volume of a cuboid length width height
This cuboid has a volume of 24 cm3. What is its
height?
2 4 height 24 cm3
8 height 24 cm3, so height 3 cm
3
Each small block measures 2 ? 2 ? 2 cm
Each small block has a volume of 8 cm3
There are 50 small blocks altogether
The volume of the shape is 400 cm3
4
Volume of a cuboid length width height
width height is the area of the cross section
So Volume of a cuboid area of cross section ?
length
5
Volume of a prism area of cross section length
Area of cross section base ? height

Cross sectional area 108 - 16 92
8
Volume of a cuboid length width height
Length 6 cm
Width 4 cm
Height 2 cm
Volume 6 4 2 48 cm3
Surface area
2 (4 2) 16 cm2 (front and back)
2 (4 6) 24 cm2 (top and bottom)
2 (2 6) 24 cm2 (two sides)
Total surface area 16 24 24 64cm2
9
Volume of a prism area of cross section ? length
Length 6 cm
Width 4 cm
Height 3 cm
Use Pythagoras to find this
Surface area
2 (½ ? 4 3) 12 cm2 (front and back)
Total surface area 12 12 30 54cm2
1 (4 6) 12 cm2 (bottom)
1 (5 6) 30cm2 (slanting side)
