To find the volume you use the formula—> length x width x height.

For the first problem you’ll solve 5 x 3 x 2 which is 30.

For the second one you’ll do the same thing. For this one you’ll do 3 x 3 x 2 which is 18.

Answer:

1) 30 units³

2) 18 units³

Step-by-step explanation:

1) The formula for volume is v = height x length x width

The height of the first object is 2, the length is 5, and the width is 3.  2 x 5 x 3 is 30, so the volume is 30 units ³.

2) Use the same formula, v = h x l x w

The height is 3, the length is 3, and the width is 2.

3 x 3 x 2 = 18

So the volume is 18 units³.

Note: Find each of the values by counting the number of squares

HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!
castortr0y [4]

Answer:

$3.75

Step-by-step explanation:

dimes= x

quarters= x+2

nickels= 2x+2

sum is 3.75

.10x+.25(x+2)+0.05(2x+2)=3.75

.10x+.25x+.50+0.10x+0.10=3.75

0.45x=3.15

x=7 dimes (0.70)

x+2=9 quarters (2.25)

2x+2=16 nickels (0.80)

They add to $3.75

a stone falls from a ledge and takes 8 seconds to the hit the ground. the stone has an original velocity of 0 m/s. how tall is t
Verizon [17]
Using equation of motion.

S = ut + (1/2)gt²

Where S = Height, t = time, g = acceleration due to gravity = 9.8 m/s²

time, t = 8 seconds 

Since it was dropped from height, initial velocity, u = 0

S = 0*t + (1/2)gt²

S = (1/2)gt²

S = (1/2)*9.8*8²  = 4.9 * 8 * 8 =  313.6

Therefore the ledge is 313.6 m tall.
