The answer is 5 1/2 or 5.5 cups because 2 3/4 doubled, or times two. Hope this helps you understand!!

There is a rectangular Prism with a Length of 12, a Width of 20, and a Height of 16. Someone says the Surface Area is 3,840. Are
SOVA2 [1]

Answer:

INCORRECT

Step-by-step explanation:

Given a rectangular prism,

Total Surface Area = 2(LW+LH+WH)

If Length = 12, Width =20, and;  Height = 16.

Total Surface Area = 2(12*20+12*16+20*16)

=2(240+192+320)

=2(752)

=1504

The Surface Area is 1504 Square Units, therefore if someone says the surface Area is 3,840, they are incorrect!

Find the velocity v(t)v(t) and speed ∥v(t)∥∥v(t)∥ of a particle whose motion is described by x=6t3−9t2,y=3,z=2t2−4t+2
Nesterboy [21]
Let \mathbf p(t)=(x(t),y(t),z(t)) denote the particle's position. Then its velocity is given by

\mathbf v(t)=\dfrac{\mathrm d\mathbf p}{\mathrm dt}=(x'(t),y'(t),z'(t))
\mathbf v(t)=(18t^2-18t,0,4t-4)

The speed is then given by the absolute value/magnitude/norm of the velocity function,

\|\mathbf v(t)\|=\sqrt{(18t^2-18t)^2+(4t-4)^2}

Area of the shaded region = area of big square minus area of little square.

Here is the set up:

Let A_s = area of shaded region.

A_s = (2x + 2)(3x - 4) - [(x - 3)(x - 6)]

Take it from here.
