To find the perimeter of something all you have to do is, MEASURE THE DISTANCE AROUND THE OBJECT, for example if you have a triangle and the left side is 8cm, the right side is 5cm, and the bottom is 3cm, add the three measurements, 8cm + 5cm + 3cm = 16cm
3 + 3 + 5 + 5 = 16cm
It is: 2*5*3 = 30 cubic cm
What is the area of a triangle with base 2cm and height 3cm
5cm 2cm
16 cm 5cm+5cm+3cm+3cm=16cm
2cm*5cm*3cm=30cm3The volume of the cuboid: 2*5*3 = 30 cubic cm
Dimensions are given out as length by width 14cm by 1cm 13cm by 2cm 12cm by 3cm 11cm by 4cm 10cm by 5cm 9cm by 6cm 8cm by 7cm And the rest is all repeats of the above.

The volume is 3cm * 2cm * 5cm = 30 cm3. The density will depend on the mass of the prism which will depend on the material that the prism is made from.
Mean = sum(X)/n = 15cm/5 = 3cm
