L=3W, H=2L, so H=6W

Since W=7, the dimensions would be:

W=7in, L=21in, H=42in

The surface area of any rectangular prism is:

A=2(LW+LH+WH), and since W=7, L=21, H=42

A=2(21*7+21*42+7*42)

A=2(147+882+294)

A=2(1323)

A=2646 in^2

The volume would be:

V=LWH, since L=21, W=7, H=42

V=21*7*42

V=6174 in^3

You question didn't really specify what you were looking for, so I did the best I could, if you need more info, just ask in the comments. :)

A trapezoid pyramid has a base area of 128 square centimeters. If it’s volume is 10,240 cubic centimeters, what is the height of
White raven [17]

Answer:

The height of the pyramid is 1.875\ cm

Step-by-step explanation:

we know that

The volume of the trapezoid pyramid is equal to

V=Bh

where

B is the area of the trapezoid base

h is the height of the pyramid

we have

B=128\ cm^{2}

V=240\ cm^{3}

substitute and solve for h

240=(128)h

h=240/(128)=1.875\ cm

How do you do this?PLZ HELP
Alisiya [41]
3(x^2+10x+5)-5(x-k)=
3x^2+30x+15-5x+5k=
3x^2+25x+15+5k

for this to be divisible by x every term must include x or get eliminated

the problematic terms are 15 and 5k
to eliminate them they must equal 0 when added:
15+5k=0
5k=-15
k=-3

so A) -3 is the solution
