2 cm by 6 cm by 8 cm

D.
6 cm by 3 cm by 4 cm;
9 cm by 4 cm by 3 cm

Answers

The dimension of the rectangular prism with different surface areas will be 2 cm by 4 cm by 9 cm. Then the correct option is B.

What is the volume of the rectangular prism?

Let the prism with a length of L, a width of W, and a height of H. Then the volume of the prism is given as

V = L x W x H

The volume of the rectangular prism is 72 cubic cm.

Then the factor of the number 72 will be

72 = 2 x 2 x 2 x 3 x 3

Then the dimension of the rectangular prism will be

L x W x H = V

L x W x H = 72

L x W x H = 2 x 2 x 2 x 3 x 3

L x W x H = 2 x 4 x 9

The dimension of the rectangular prism with different surface areas will be 2 cm by 4 cm by 9 cm. Then the correct option is B.

More about the volume of the rectangular prism link is given below.

#SPJ6

The answer is B
volume of rectangular prism = (area* height )
so 2 * 4 * 9 = 72 cm3
9* 4 * 2 = 72 cm3
but they have differant surface area

Write the given expression as the sine of an angle
sin40cos20+cos40sin20

Answers

It's $sin(40+20)=sin60=\frac{\sqrt3}2$

Yo sup??

The given expression is in the form

sinAcosB+cosAsinB

we know that

sin(A+B)=sinAcosB+cosAsinB

therefore

sin40cos20+cos40sin20=sin(40+20)

=sin60

=√3/2

Hope this helps.
