Oh, honey, it looks like you've got yourself a rectangular prism there. To find the surface area, you calculate 2lw + 2lh + 2wh. So, for your dimensions of 7cm, 5cm, and 8cm, the surface area would be 2(75) + 2(78) + 2(5*8) = 10 + 112 + 80 = 202 square centimeters.
8x5x7=280 add the units so answer is 280cm
The area for a 7cm by 8cm is 56.
If one side of the triangle is 8cm then the other side is 7cm because 0.5*8*7 = 28 square cm
The curved surface area of a cylinder with a height of 8cm and diameter of 10cm is 251.33cm2
7cm because if the mm was 5 or over then it would be closer to 8cm but it is lower than 5 so it is closer to 7cm.
Find the area of 5cm 12cm 8cm
It is either a triangle on a curved surface or a polygon with 4 or more sides.
This cone has a lateral surface area of approximately 226.73cm2
8x5x7=280 add the units so answer is 280cm
The area for a 7cm by 8cm is 56.
105cm2
The answer is, you can draw a rectangle with these measurements: 6cm and 9cm 5cm and 10cm 7cm and 8cm
area = 8*5 = 40 square cm
If one side of the triangle is 8cm then the other side is 7cm because 0.5*8*7 = 28 square cm
The curved surface area of a cylinder with a height of 8cm and diameter of 10cm is 251.33cm2
You measure the sides of the shape you are finding the perimetre of and then add together the measurements. Then you have your answer. eg: 8cm x 7cm x 3cm x 5cm 8+7+3+5=23 answer is 23cm
7cm because if the mm was 5 or over then it would be closer to 8cm but it is lower than 5 so it is closer to 7cm.
