Draw each side of the open box individually, or you could draw a net of the shape. Individual drawings of each side may be easier. Make sure to label the shapes you draw to make sure you do not accidentally do it twice.
calculate the area of each of the shapes that have been drawn, then sum the areas which will give you the TSA
Total surface area = (2*pi*radius2)+(pi*diameter*height)
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.
Another dimension is needed to work out the surface area of the roof.
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
Work out each area of the 5 faces individually and then add them together.
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?
surface area prism = 2 × area end + total area side = 2 × area end + perimeter end × length of prism The information given to you will allow you to work out the area of one pentagonal end, and the perimeter of the pentagonal end.
A quadrilateral does not have a surface area because it is not a voluminous figure.
To work out the area of the rectangular faces, you need to multiply the length by the width. You then need to multiply that answer by 3 (because there are 3 rectangular faces).To work out the area of the triangular faces, multiply the base of the triangle by the height and divide the answer by 2 (to find the area of one triangle). You then need to multiply it by 2 again because there are 2 triangular faces.Important: The height of a triangle is the distance from the top corner of the triangle down to the base (so that it meets the base at 90 degrees)You then need to add the total surface area of the rectangular faces to the surface area of the triangular faces to get the total surface area of the entire prism.(sorry for the essay :])
Work out the surface area of its 6 faces individually and then add them together
Find the area of one of the sides and then multiply it by 3 (3 sides to a triangular pyramid)Then work out the area of the base of the pyramid, and add it to the total area of all the sides.Area of a triangle = Base x Height / 2
You will have to work the surface area of one of the ends and then multiply that with the length.
