This is a cuboid so it has six sides. The surface area is the sum of the areas of the sides.

Opposite sides are the same. So we have:

2 sides of area 8 x 9 centimetres squared

2 sides of area 8 x 5 centimetres squared

2 sides of area 9 x 5 centimetres squared

That's a total of 314 centimetres squared.

how do you find the volume of the surface area of the solid 6 feet round 5 inches height and 7 inches long?

"volume of the surface area" is garbled: by definition an area is a two-dimensional measurement and so has a volume of zero. Was that "volume AND the surface area"? Anyway the simplest way to determine this is to just wait for your teacher to reveal the answers to the homework exercises, since that's surely where this comes from...


Why do you need to find the surface area of a cube?

length of a side.If a side Y long. Surface area =Y x Y x 6


What is the surface area of a cube with edges x cm long?

To find the surface area of a cube, add the area of its 6 sides. The area of one side is x^2. The cube has 6 faces therefore the surface area equals 6x^2


What is the surface area of a cube if the edges are 10cm long?

How do you find the total area of a solid?

To find the total area of a solid, the general formula is SA=(base area)+(perimeter of one face*height). To put it more simply, if you had a cube with edges 3 inches long, your formula would look like this: Area=(3*3)+(6*3), and the answer would be 27 inches squared.


How long does solid take to melt?

The time it takes for a solid to melt depends on several factors, including the material's melting point, the amount of heat applied, and the solid's mass and surface area. For example, ice will begin to melt at 0°C (32°F), but the rate of melting can vary significantly based on the temperature of the surrounding environment and the method of heating. Generally, a solid will melt faster if it is in smaller pieces or has a larger surface area exposed to heat.


How do you find the surface area in a oval?

What are the three dimensions of solid?

The three dimensions of a solid are length, width, and height. These dimensions define the space that a solid object occupies in three-dimensional space. Length refers to how long an object is, width indicates how broad it is, and height measures how tall it is. Together, these dimensions help in calculating the volume and surface area of the solid.


Find the surface area of a cube whose volume is 343m cube?
