The ratio of the heights of two similar pyramids is 4: 7. the volume of the smaller pyramid is 1,331cm3. to the nearest whole number, what is the volume of the larger pyramid?
a) 154cm3
b) 7,133cm3
c) 14,641cm3
d) 18,643cm3

Option B-  7,133 cubic cm is the answer.

Step-by-step explanation:

Ratio of volumes V1 (smaller pyramid) and V2 (larger pyramid) of the pyramids is equal to the ratio of the cubes of heights of the pyramids.

Let the volume of larger pyramid be x

The volume of the smaller pyramid is given as 1,331 cm³

The ratio equation forms:

x=7133.32 ≈ 7133 cubic cm.

answer: 370

step-by-step explanation:

remember use pemdas! there are no parentheses or exponents so lets move onto the first part of the equation: multiplication and division. first, lets break the first part of the equation up into something easier using the distributive property. 28 * 12= (20 *12) + (8*12) you know that 20*12 is 240 and 8*12 is 96. add them and you get 336. then, lets solve the last part of the equation (the last part of pemdas is addition and subtraction). 336 plus 34 is 370. hope this !
