A rectangular prism has a height of 8cm, a length of 4cm, and a width of 3cm. The prism is enlarged by a scale of 2. Find the surface area ratio of the enlarged prism to the original prism

The area of enlarged prism is 4 times surface area of original prism.

Step-by-step explanation:

We have been given that a rectangular prism has a height of 8 cm, a length of 4 cm, and a width of 3 cm. The prism is enlarged by a scale of 2.

Let us find total surface area of original prism as:

Since the prism is enlarged by a scale of 2, so each side of new prism would be 2 times grater than side of original prism as:

Length: 8 cm

Width: 6 cm,

Height: 16 cm.

Let us find ratio of surface area of the enlarged prism to the original prism as:

Therefore, the area of enlarged prism is 4 times surface area of original prism.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.
