To find the surface area of the rectangular prism, use the formula:
A=2(wl+hl+hw)
Note that: w = 4, l = 12, h = 3
plug into the equation
A = 2((4)(12) + (3)(12) + (3)(4))
Simplify
A = 2(48 + 36 + 12)
A = 2(96)
Multiply
A = 96 x 2
A = 192
192 m³ is the surface area of the rectangular prism.
hope this helps
The correct answer would be C. I am 100% shure
Ddddddddddddddddddddddddddddddddddddddd
For this case we have the following vector:
v = (- 2, -1).
Using product point we have:
v.v = (-2, -1). (- 2, -1)
v ^ 2 = (-2) * (- 2) + (-1) * (- 1)
v ^ 2 = 4 + 1
v ^ 2 = 5
Then, clearing the module we have:
v = root (5)
Answer:
The module of the vector is given by:
v = root (5)
C. square root of 5
