a rectangular pyramid has a volume of 190 cubic centimeters. Find two possible sets of measurements for the base area and height

DerKrebs [107]

<h3>One possible set for the base area and height of the pyramid is 570 cm and 1 cm respectively</h3><h3>Other possible set for the base area and height of the pyramid is 285 cm and 2 cm respectively</h3>

<em><u>Solution:</u></em>

<em><u>The volume of rectangular pyramid is given as:</u></em>

$Volume = \frac{1}{3} \times base\ area \times height$

Given that,

<em><u>Rectangular pyramid has a volume of 190 cubic centimeters</u></em>

<em><u></u></em> $190= \frac{1}{3} \times base\ area \times height$ <em><u></u></em>

<em><u>Substitute, base area = 570 and height = 1</u></em>

Then we get,

$190 = \frac{1}{3} \times 570 \times 1\\\\190 = 190$

Thus one possible set for the base area and height of the pyramid is 570 cm and 1 cm respectively

<em><u>Substitute, base area = 285 and height = 2</u></em>

$190 = \frac{1}{3} \times 285 \times 2\\\\190 = \frac{1}{3} \times 570\\\\190 = 190$

Thus other possible set for the base area and height of the pyramid is 285 cm and 2 cm respectively

What is the landing strip’s area ?

attashe74 [19]

Answer:

D

Step-by-step explanation:

The perimeter P of a rectangle is calculated as

P = 2l + 2w ( l is the length and w the width ) , then

2l + 2(9) = 5364

2l + 18 = 5364 ( subtract 18 from both sides )

2l = 5346 ( divide both sides by 2 )

l = 2673

Then

A = lw = 2673 × 9 = 24057 m² → D
