if you are finding the surface area of a cube, first find the area of one side by multiplying length X width and then multiply the area of one side of the cube by 6. that would be the surface area of the cube
To find the area of a shape, we need to know the shape of the object. If the object is a square, we can use the formula A = s^2, where A is the area and s is the length of one side. If the object is a circle, we can use the formula A = πr^2, where A is the area and r is the radius. Without knowing the shape of the object, we cannot calculate the area of 42.5 cm.
Its side!
if the object is a square take the square root of the area, which gives you one side length. Then multiply by 4. In this case the side length would be 15 and the perimeter would be 60.
Volume is how much an object can store - like how much can you put inside a box. Surface area is the sum of the area of an objects surfaces - such as if you have a box, find the area of one side. Then you just multiply it by 6 (because a box have 6 faces) to get the total area of an object's surface.
