How many cubes with side lengths of 1/2 cm does it take to fill up the prism

ELEN [110]

24 cubes can filled up the prism

Solution:

The image of the question is attached below.

Given data:

Length of the prism = 2 cm

Breadth of the prism = 1 cm

Height of the prism = $$\frac{3}{2}$ cm

Volume of the prism = length × breadth × height

$$=2\times 1\times \frac{3}{2}$

$=3$ cubic cm

Volume of the prism = 3 cubic cm

Side length of the cube = $$\frac{1}{2}$ cm

Volume of the cube = side × side × side

$$=\left(\frac{1}{2}\right)^{3}$

$$=\frac{1}{8}$ cubic cm

Volume of the cube = $\frac{1}{8}$ cm

$$\text{Number of cubes} =\frac{\text{Volume of the prism}}{\text{Volume of the cube}}$

$$=\frac{3}{\frac{1}{8} }$

$=3\times8$

$=24$

Number of cubes = 24

Hence 24 cubes can filled up the prism.

If tan theta= 15/8, then:

Maurinko [17]

Hello there!

The only thing we have to do here is remember our trigonometric functions!

sin=y/r
cos=x/r
tan=y/x
sec=r/x
csc=r/y
cot=x/y

Knowing that tanᎾ=15/8, we know that y=15 and x=8

Now we need to look at the answer choices and see if they are correct.

A. secᎾ=17/8
Since secᎾ=r/x and r=17 and x=8, this is correct.

B. cosᎾ=15/17
Since cosᎾ=x/r and x=8 and r=17, this is wrong.

C. cotᎾ=8/15
Since cotᎾ=x/y and x=8 and y=15, this is also correct!

D. cscᎾ=17/15
Since cscᎾ=r/y and r=17 and y=15, this is right too.

I really hope this helps!
Best wishes :)
