Find the sum of the value of 8 in 387,562 and the value of 7 in 7,328,562

MAXImum [283]

387,562
The 8 is in the ten thousands place, so it equals 80,000.

7,328,562
The 7 is in the millions place, to it equals 7,000,000.

The sum is the value of two numbers added together (the answer to an addition problem).

80,000 + 7,000,000 = 7,080,000

A regular square pyramid has base edges of length 16 and its lateral faces are inclined 30° to the base of the pyramid. What is

Helga [31]

Answer:

1) $h=\frac{8\sqrt{3}}{3}\ units$

2) $V=\frac{2,048\sqrt{3}}{9}\ units^3$

Step-by-step explanation:

Part 1) Find the height of the pyramid

we know that

$tan(30^o)=\frac{h}{(b/2)}$

where

h is the height of the pyramid

b is the length side of the square base

we have

$tan(30^o)=\frac{\sqrt{3}}{3}$

$b=16\ units$

substitute

$\frac{\sqrt{3}}{3}=\frac{h}{(16/2)}$

$\frac{\sqrt{3}}{3}=\frac{h}{8}$

$h=\frac{8\sqrt{3}}{3}\ units$

Part 2) Find the volume of the pyramid

we know that

The volume of the pyramid is equal to

$V=\frac{1}{3} Bh$

where

B is the area of the square base

h is the height of the pyramid

we have

$B=(16^2)=256\ units^2$

$h=\frac{8\sqrt{3}}{3}\ units$

substitute

$V=\frac{1}{3} (256)(\frac{8\sqrt{3}}{3})$

$V=\frac{2,048\sqrt{3}}{9}\ units^3$

How would you explain surface area and volume to a 6th grader who is just now learning about these concepts?

AnnyKZ [126]

Answer: Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area. you should explain with a net its easier.

hope this helps and sorry bout the smack comment lol
