  • Determine the surface area of the right square pyramid.

\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}

The formula for finding the surface area of a right square pyramid is ⇨ b² + 2bl, where

  • b = base of the right square pyramid
  • l = slant height of the right square pyramid.

In the given figure,

  • base (b) = 4 ft.
  • slant height (l) = 8 ft.

Now, let's substitute the values of b & l in the formula & solve it :-

\sf \: {b}^{2}  + 2bl \\  =   \sf \: {4}^{2}  + 2 \times 4 \times 8 \\  =  \sf \: 16 + 8 \times 8 \\  =  \sf \: 16 + 64 \\  =  \huge\boxed{\boxed{ \bf 80 \: ft ^{2} }}

So, the surface area of the right square pyramid is <u>8</u><u>0</u><u> </u><u>ft²</u><u>.</u>

Rachel and her friends are making necklaces out of beads and straws. They plan to use 12 beads and 5 straws for each necklace. T
bagirrra123 [75]

Answer:

225 necklaces.

Step-by-step explanation:

Assuming that they have the necessary amount of straws to match the beads then we can use the following simple equation to solve this problem.

t = b/12  ... where t is the total amount of necklaces and b is the number of beads you have

t = 2700 / 12

225 necklaces.

For 225 necklaces you would also need 1125 straws since each necklace requires 5 straws to be fully made. Therefore if you have this amount you should not run into any problems.

Aaron bought a set of plastic ice cubes with a mixture of water and air inside.
LekaFEV [45]

Answer:

Volume of water and air is 3,000 mm³

Step-by-step explanation:

Given:

Length of base = 15 mm

Width of base = 20 mm

Height of figure = 30 mm

Find:

Volume of water and air is inside each of the plastic ice cubes.

Computation:

Height of each rectangular pyramid = Height of figure / 2

Height of each rectangular pyramid = 30 / 2

Height of each rectangular pyramid = 15 mm

Volume of each rectangular pyramid = lbh / 3

Volume of each rectangular pyramid = [15 × 20 × 15] / 3

Volume of each rectangular pyramid = [4,500] / 3

Volume of each rectangular pyramid = 1,500 mm³

Volume of water and air is inside each of the plastic ice cubes = 2 × Volume of each rectangular pyramid

Volume of water and air is inside each of the plastic ice cubes = 2 × 1,500

Volume of water and air is inside each of the plastic ice cubes = 3,000 mm³

sveticcg [70]

Answer:

<1 = 33 degrees

<2 = 33 degrees

<3 = 114 degrees

Step-by-step explanation:

<1 and <2 = x

<3 = 3x+15

<1 + <2 + <3 = 180 degree

x + x + 3x + 15 = 180

5x = 180 - 15

x = 165/5

x = 33

<3 = 3(33)+15

= 114 degrees
