this method works for any shape which is 3-D first find the formula of the shape lets say a cuboid (rectangular block) or known as rectangular prism its formula is
H x W x L (Height x Width x length)
lets say H=4
and W=30
finally L=15
15 x 30=450 so add 450+ 60+120=630
15 x 4=60 times it by two =1260 now minus the first number you got
4 x 30= 120 and there is your answer
1260-450=810
Answer=810
This was from the book bond Assesment book paper 4 question 25 thats how you work out Surface Area
What else can I help you with?
How do you work out the total surface area of the cylinder?
Total surface area = (2*pi*radius2)+(pi*diameter*height)
If the width of the roof is 26ft what is the total area of the roof?
Another dimension is needed to work out the surface area of the roof.
Does the surface of your area describe area or perimeter?
Kinda of a combination of both. The surface of a 3-D object is called surface area.
How does surface area different area?
surface area is basically the total area of each surface of the 3d object. Sa = 2-D A = 3-D
Find the surface area of a plate?
surface area of glass plate
How does surface area work?
It would help if the question was less obscure. What do you mean by "work"? How the surface area affects chemical processes (for example the surface area of catalysts), or diffusion, or surface areas and friction?
What is a formula to work out the surface area of a quadrilateral?
A quadrilateral does not have a surface area because it is not a voluminous figure.
How do you find the surface area of a rectanguar prism?
Work out the surface area of its 6 faces individually and then add them together
How do you work out the total surface area of the cylinder?
Total surface area = (2*pi*radius2)+(pi*diameter*height)
How do you work out the volume of prism?
You will have to work the surface area of one of the ends and then multiply that with the length.
What is the Total surface area of a Toblerone?
Form a net of the Toblerone and work out the area of each individual part of it and then add up the parts together to find its entire surface area
What is the surface area of a prism whose bases each have an area 16 meters squared and whose lateral surface area is 64 meters squared?
work it out
If the width of the roof is 26ft what is the total area of the roof?
Another dimension is needed to work out the surface area of the roof.
How do you find the surface area of a triangular prism net?
Work out the area of each of the 5 nets and then add them together
What is the surfqace area of a cylinder?
It is the surface area of the two ends plus the surface area of the curved surface. Surface area of each end is pir2 Surface area of the curved surface is 2pirh Total surface area = 2pir2 + 2pirh
What is the surface area is the sum of the areas of all the surfaces of a three dimensional object called?
The total surface area! The total surface area! The total surface area! The total surface area!
What is the total surface area of a cylinder with hemispherical ends?
Two hemispherical ends = 4*pi*radius2 Lateral surface area of the cylinder = 2*pi*r*lenght of cylinder Work both out separately and the sum of them will give you the total surface area in square units.
