Peter is covering a box to mail. The dimensions of the base are 5 inches by 3 inches and the height
is-8 inches. How much paper will he need to totally
cover it?

158 inch^2

Step-by-step explanation:

To know how much paper he needs, we need to find the surface area of the box he wants to mail and thats the amount of paper.

Surface area of cuboidal box:

= 2( lh+bh+lb)

where l is length

b is breadth

h is height

= 2( 5*3+8*3+5*8)

= 2 ( 15+24+40)

= 2*79

= 158 inch^2 of paper

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

3; 9 is 8 to -4
