What is the surface area of a tissue box with a length of 8 inches, a width of 4 inches, and a height of 3 inches?

The box has 6 sides. 2 each of 8 x 9, 8 x 12 and 9 x 12 ie 2 x (72 + 96 + 108) ie 2 x 276 which is 552 sq ins.

Step-by-step explanation:

136

Step-by-step explanation:

The method is 2lw x 2lh x2wh

2x8x4

2x8x3

2x4x3

= 136

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)

step-by-step explanation:

distance formula is d=√(x2-x1)^2   +   (y2-y1)^2
