how do u calculate...?

Question

how do u calculate the surface area and volume. really need the help quickly plz
thx in advance

i am calculating a jelly cube

Answer 1

The volume of a cuboid (ie shape with all rectangular sides) is just height x length x width.

To get the surface area, work out the areas of each rectangular face (length x width) and add them together.

Answer 2

To calculate the surface area, times the length by the width.

And for volume, times the length by the width by the depth.

Hope this helps.

Answer 3

Volume can be calculated from area of the base multiplied by its height.Surface area can be calculated by calculating the area of the developed surface. The developed surface depends upon the shape of the solid body.

Answer 4

surface area of:
square and rectangle is L x W
Triangle is: 0.5 x (L x W) assuming one of the corner is 90 degree
Circle is: pi x r

to work out the volumn you just multiply it by the H

L = length
W = Width
r = radius
pi = 3.14
H = height

hope this helps

Answer 5

It would be nice if there were a single formula that worked for every shape, but there is not. You need to know what shape you are doing - a sphere, a cube, something else?

Answer 6

Assume jelly cube to be 20mm then 20x20x20 cubic millimetres or 8000cubic millimetres

Answer 7

length x width x height for volume
if it's a perfect cube then, SA = 6 x length x length

Answer 8

Surface area = lenghth x width

Volume = l x b x w

ok.

Answer 9

With a calculator.

Answer 10

Stick a ruler on your head, add a carrot, then subtract an orange..voila!
