The surface area (SA) of a rectangular prism (box) is obtained by the equation,
SA = 2 (LW + WH + LH)
where L is length, W is width, and H is height.
Substituting the values for the dimensions,
SA = 2 (15cm x 22cm + 22cm x 9cm + 15cm x 9 cm) = 1326 cm²
Thus, the surface area of the box is 1326 cm².
Dividing is the opposite of Multiplying.
If you multiply 9 * 1 = 9.
So if you Divide N by 9 the answer would be 1.
I hope this helped. ^_^
Answer:
4
Step-by-step explanation:
To find the scale factor divide the new length by the original.
10/ 2.5 = 4
The scale factor is 4.
Multiply each term in the first set of parentheses by each term in the second set, then combine like terms.
7x x 3x^2 = 21x^3
7x x -4x = -28x^2
7x x 5 + 35x
-6 x 3x^2 = -18x ^2
-6 x -4x = 24x
-6 x 5 = -30
Combine like terms to get:
21x^3 - 46x^2 + 59x - 30
Answer:
Step-by-step explanation:
Solved by elim: it is similar (diff size, but not congruent, same size) and B is twice the size of A, not half.
