Martin builds a right square pyramid using
straws. a diagram of the pyramid and its net
are shown.
what is the surface area of the pyramid?
enter the answer in the box.

360 ft^2

Step-by-step explanation:

The surface area of a right square pyramid can be found using the formula:

In this formula:

In this diagram, the base edge length is 10 ft and the height of the square pyramid is 12 ft. Substitute these values into the formula to find the surface area.

Simplify this expression. Start by evaluating the exponents then rewrite the expression.

Now evaluate inside the radical sign.

Multiply 2 and 10 together (we're following the rules of PEMDAS).

Find the square root of 169 then multiply that by 20.

Finish the problem by adding 100 and 260 together.

The surface area of the pyramid is .

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
