Answer:

52 cm^2

Step-by-step explanation:

To find the rectangular area on the bottom you multiply 3 by 5 = 15 cm^2.

To find the triangular area on the sides you multiply 4 by 3 = 12 cm^2 then divide by 2 = 6 cm^2, but since there are 2 of them you multiply by 2 again and end up with a surface area of 12 cm^2.

To find the square area on the top you multiply 5 by 5 = 25 cm^2.

So the total surface area is 25+15+12 = 52 cm^2.

<em>Note: cm^2 represents cm squared</em>

What is the volume of this square pyramid?

tatuchka [14]

Answer: 1296 cm³

Step-by-step explanation:

Since, the volume of a square pyramid is,

$V = \frac{a^2h}{3}$

Where a = side of the square base,

h = height of the pyramid,

By the given diagram,

a = 18 cm,

h = 12 cm,

Hence, the volume of the given pyramid,

$V = \frac{18^2\times 12}{3}$

$= \frac{324\times 12}{3}$

$=\frac{3888}{3}$

$=1296$ cube cm.

⇒ First option is correct.

Solve for p -6p+7=3(2p-3)-4(-10+4p

ozzi

p-6p+7=3(2p-3)-4(-10+4p

We move all terms to the left:

p-6p+7-(3(2p-3)-4(-10+4p)=0

We add all the numbers together, and all the variables

p-6p-(3(2p-3)-4(4p-10)+7=0

We add all the numbers together, and all the variables

-5p-(3(2p-3)-4(4p-10)+7=0
