Answer 2

The formula is A = 2(wl + hl + hw) Where w = width, h = height, and l = length.

We know that
w = 512mm

l = 80mm

h = 40mm

So we have to plug in the values in the formula

A = 2(512×80 + 40×80 + 40×512)

Answer 3

We can convert 512 to 5.5 to make things easier

A = 2(5.5×80 + 40×80 + 40×5.5)

Answer 4

A = 2(5.5×80 + 40×80 + 40×5.5)

We have to do what is int he parenthesis first, and in the parenthesis we have to do all the multiplication first starting from the left side of the equation

A = 2(5.5×80 + 40×80 + 40×5.5)

Answer 5

so 7720 right?
