A right square pyramid is pictured below. if l is 15 cm and x is 18 cm, what is the surface area of the pyramid?

Nady [450]

Answer:

The surface area of square pyramid is 953.64 cm² .

Step-by-step explanation:

Given as for a square pyramid :

The height of pyramid = l = 15 cm

The base of square pyramid = x = 18 cm

Now,

The surface area of square Pyramid = $b^{2} + 2b\times \sqrt{\frac{b^{2}}{4}+h^{2}}$

or , The surface area of square Pyramid = $x^{2} + 2x\times \sqrt{\frac{x^{2}}{4}+l^{2}}$

Or, The surface area of square Pyramid = $18^{2} + 36\times \sqrt{\frac{18^{2}}{4}+15^{2}}$

Or, The surface area of square Pyramid = 324 + 36 × $\sqrt{81 + 225}$

or, The surface area of square Pyramid = 324 + 36 × 17.49

Or , The surface area of square Pyramid = 324 + 629.64 = 953.64 cm²

Hence The surface area of square pyramid is 953.64 cm² . Answer

The faces of a cube are to be numbered with integers 1 through 6 in such a way that consecutive numbers are always on adjacent f

Blizzard [7]

Answer:

Total different ways to number the remaining faces is 10.

Step-by-step explanation:

It is given that consecutive numbers are always on adjacent faces (not opposite ones).

The face numbered 1 is on top and the face numbered 2 is toward the front.

Top = 1

Front = 2

The remaining faces are left right bottom back. Total possibilities are shown below.

S.no. 3 4 5 6

(1) Right Back Bottom Left

(2) Right Back Left Bottom

(3) Right Bottom Left Back

(4) Right Bottom Back Left

(5) Bottom Right Back Left

(6) Bottom Left Back Right

(7) Left Back Bottom Right

(8) Left Back Right Bottom

(9) Left Bottom Right Back

(10) Left Bottom Back Right

When Bottom=3, then we can not place 4 on back because doing this 5 and 6 are opposite ones.

Therefore, total different ways to number the remaining faces is 10.
