What is the surface area of a square pyramid if the base has an area of 16 cm2 and the lateral faces have a slant height of 12 cm? 112 cm2 208 cm2 400 cm2 640 cm2

Option 1 - 112 cm.sq.

Step-by-step explanation:

Given : The base has an area of square pyramid 16 cm sq. and the lateral faces have a slant height of 12 cm.

To find : What is the surface area of a square pyramid?

Solution :

First we find the side of the square.

The base has an area of square pyramid is 16 cm.sq.

The side of the pyramid is a=4

Now, The lateral surface area of the square pyramid is the multiplication of half into perimeter of square into slant height.

The total surface area of the square pyramid is multiplication of lateral surface area into area of base.

Therefore, Option 1 is correct.

The surface area of a square pyramid is 112 cm.sq.

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
