No, you must add, not multiply.
you are suppose to MULTIPLY on area.
Find the circumference of the circles (the ends) and multiply it by the height of the cylinder. Then add that to the area of the ends.
You have to multiply to find area you have to add to find perimiter
False. You must find the area of each of the faces, then add those together.
To find the perimeter you add and to find the area we multiply.
NO. This is the way to get the volume of a prism, not the surface area of any three-dimensional figure. To find the surface area of a three-dimensional figure, you must find the area of each of its faces and then add the side-areas together.
False.To find the surface area of a three-dimensional figure, find the area of the faces and add them together.
No because you multiply the dimensions
You should break it down in to smaller shapes. Two rectangles. Then figure out all the lengths. Multiply to find the area of the two rectangles. then add the products to get the final area.
It isn't clear what exactly you want to calculate. To calculate total area, you can add different individual areas (different pieces of a figure).
you would find the area of each side and then add them together
Multiply l by 7 then add 1 to find the area
... face and add them together.
TRUE: To find the surface area of a three dimensional figure, you must find the area of each of its faces and then add them together.
If you want to find the area of a rectangle (inclusively a square), rhombus, or parallelogram, you multiply.
measure, add, subtract, multiply, find area, figure how many boards to buy, how much roofing to use, how much insulation to use.
The perimeter is the length around something, add all sides together to get the length of the perimeter.
for area you times the two numbers and for perimeter you add the numbers
Break it down into smaller shapes, find the area of those bits, then add them all together.
to find the perimeter you must add all sides. and to find area you have to multiply lenght and width
Find the length of the two sides of base. Add the two numbers. Then multiply by 2.
To find the surface area of a square (or rectangle) you multiply the length times the width. Then to get the total area of a cube you add up the surface areas of all the square sides it has. I hope you can figure it out from there.
