The dimensions of a rectangular prism are shown below. Length 1 1/3 feet Width 1 foot length 2 1/3 feet. The lengths of the side

zysi [14]

Answer:

84 cubes

Step-by-step explanation:

Given,

The dimension of the rectangular prism are,

$1\frac{1}{3}\text{ ft }\times 1\text{ ft }\times 2\frac{1}{3}\text{ ft }$

Hence, the volume of the prism,

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

$=\frac{4}{3}\times \frac{7}{3}$

$=\frac{28}{9}\text{ cube ft}$

Now, the volume of a cube = side³,

If side = $\frac{1}{3}$ ft,

Then the volume of each cube,

$V'=(\frac{1}{3})^3=\frac{1}{27}\text{ cube ft}$

Hence, the number of cubes that can be packet in the prism

$=\frac{V}{V'}$

$=\frac{28/9}{1/27}$

$=\frac{27\times 28}{9}$

$=3\times 28$

$=84$

Pani-rosa [81]

Answer:

h = 19cm

Step-by-step explanation:

The area of a parallelogram =

A = bh

285cm² = 19×h

285 = 19h

divide by 19

285/19 = 19h/19

h = 15cm

A group of adult males has foot lengths with a mean of 26.88 cm and a standard deviation of 1.13 cm. Use the range rule of thumb

kompoz [17]

Answer:

The adult male foot length of 24.3 cm is significantly low.

Step-by-step explanation:

We have been given that a group of adult males has foot lengths with a mean of 26.88 cm and a standard deviation of 1.13 cm. We are asked to find the range rule of thumb to determine whether he adult male foot length of 24.3 cm significantly low or significantly high.

The range rule of thumb states that usual values in a normal standard deviation lies within 2 standard deviation from mean that is $\mu-2\sigma$ , where $\mu=\text{ Mean and }\sigma=\text{Standard deviation}$ .

Let us find the range of possible values.

$28.88-2(1.13)$

$28.88-2.26$

$26.62$

Since 24.3 is less than lower value of range (26.62), therefore, the adult male foot length of 24.3 cm is significantly low.
