Aright rectangular prism has a lenghth of 6cm, a width of 8cm, and a height of 4cm. the dimensions of the prism are doubled. what is the surface area of the enlarged prism? enter your answer in the box.

The formula for the surface area for a rectangular prism is:

A = 2(wl+hl+hw)

Where:
w = width
l = length
h = height

If you double the dimensions, all you need to do is multiply the dimensions by 2.

w = 8 cm * 2 = 16 cm
l = 6cm * 2 = 12 cm
h = 4cm * 2 = 8 cm

Now put those in the equation:

A = 2(wl + hl + hw)
    = 2((26)(12)+(8)(12)+(8)(16))
    =2 (312 + 96 + 128)
    = 2(536)
    = 1,072 cm^2

You want the answer to all

It’s either a or c as the answer.
