If the dimensions of the prism are doubled the surface area of the enlarged prism is 640 cm²

<h3>Surface area of a rectangular prism:</h3>
  • Area = 2lw + 2lh + 2wh

where

h = height

l = length

w = width

Therefore, if the dimension of the prism are doubled the new dimension will be as follows:

l = 5(2) = 10 cm

w = 2(2) = 4 cm

h = 10(2) = 20 cm

Therefore,

surface area = 2(10 × 4) + 2(10 × 20) + 2(20 × 4)

surface area = 2(40) + 2(200) + 2(80)

surface area = 80 + 400 + 160

surface area = 640 cm²

Can you help me with this, please? ​
Aloiza [94]

Answer:

y =x-12

Step-by-step explanation:

(x_1, y_1) = (16, 4) \ \ \ and \ \ \ (x_2, y_2) = (17, 5)

Equation of straight line is

y-y_1 =\frac{y_2-y_1}{x_2-x_1}  (x-x_1)

y-4 =\frac{5-4}{17-16}  (x-16)

y =(x-16)+4

y =x-12

Cloud [144]

Answer:

Devin will need 9 cubes of wax.

Step-by-step explanation:

To find the volume of the pyramid, you use (area of the base)* height of the pyramid divided by 3. You know the volume of a cube of wax is 32 cm^3. The volume of your pyramid is 270 cm^3. 270/32=8.4375.

Once you get 8.4375 cubes, you round to the next whole number, which is nine.
