Case 1, Consider cuboids having equal volumes and the following dimensions:
1) Length= 20cm, Breadth= 10cm, Height= 5cm
2)Length= 10cm, Breadth= 10cm, Height= 10cm
3)Length= 100cm, Breadth= 5cm,Height= 2cm

Step 1, Calculate of each cuboid:
Volume= lbh
Surface area=2(lb+bh+hl)

Step 2, Express this calculation in a table:
Cuboid 1 Cuboid 2Cuboid 3
Length 20cm 10cm 100cm
Breadth 10cm 10cm 5cm
Height5cm 10cm 2cm
Volume 1000cubic cm 1000cubic cm 1000cubic cm
Surface Area 700sq cm600sq cm 1420sq cm

Step 3, Write your conclusions guide by the following helpful questions:
· What relation do you found between the volumes of the three samplecuboids?
· What relation do you found between the surfaces areas of the three sample cuboids?
· Are they different, equal, related, doubled, greater, smaller, or something else?
· Which has theminimum surface area? And base on its lengths, how is it called, or what form does it has?

Case 2, Consider cuboids having equal volumes and the following dimensions:
1) Length= 14cm, Breadth= 6cm,Height= 5.4cm
2)Length= 8cm, Breadth= 8cm, Height= 8cm
3)Length= 16cm, Breadth= 6.4cm, Height= 4cm

Step 1, Calculate of each cuboid:
Volume= lbh
Surface area=2(lb+bh+hl)

Step 2, Express thiscalculation in a table like the following sample:
Cuboid 1 Cuboid 2 Cuboid 3
Length 14cm 8cm16cm
Breadth 6cm 8cm 6.4cm
Height 5.4cm 8cm 4cm
