Below is the solution:
A(final)=16cm^2 ds/dT=6 da/dT=?
<span>A=(s)^2 A=16cm^2 , s=sqrt(A) , s=sqrt(16) , s=4cm </span>
<span>da/dT=2(s)(6cm/sec) , da/dT=12cm/sec(s) , da/dT=12cm/sec (4cm)
</span>
<span>Answer should be da/dT=48cm^2/sec

Correct question:
Beth is making a beanbag seat in the shape of a cube. Each side of the seat is 2 feet long. Beth needs to find the volume of the seat so that she can buy the correct amount of beans. Beans are sold in bags that hold 2³ feet of beans. How many bags of beans should Beth buy?
Answer:
Beth should buy 4 bags of beans.
Step-by-step explanation:
Since Beth is making a bean bag seat in the shape of a cube, we already know the bean bag seat is a cuboid.
Also, we are asked to find the volume of a cuboid, and the volume of a cuboid is given as the product of all dimensions of the cuboid.
Therefore the volume of the seat is expressed as
V = 2 * 2 * 2
V = 8
To find the number of bags she needs, we have:
Beth needs to buy 4 bags of beans
