Answer 2

is that a regular square pyramid seen from above?

Answer 3

yes

Answer 4

do they mean surface area?

Answer 5

yes

Answer 6

ok :)

let's first find the area of the base

that would be a square with a side length of 4

Answer 7

Area of a Square = (side)*(side) = 4 * 4 = ?

Answer 8

16

Answer 9

good :)

then let's find the Area of one of the Triangles :3

We need the height of it
we are given that the hypotenuse is 4
and half the base (to make a right triangle) is 2

so square root of (4^2 - 2^2) = ?

Answer 10

12

Answer 11

square root of 12

that's right ^_^

it can be simplified to 2 squareroot of 3

then there are 4 triangles
so times 4

gives us\[\large 8\sqrt{3}\]

Answer 12

are your options in decimals? :)

Answer 13

we will have to add that 8 root(3) + 16
