Figures and cross section
Using a cereal box, find the surface area and the box's volume. The dimensions are 8 inches wide by 12 ⅛ inches tall by one ¾ inch deep. Parallel to the base, it would be a rectangle 8 inches x 1 ¾ inches.
Surface area = 2x(12 ⅛ x8) + 2 x (8 x 1 ¾) =2 x ( 12 ⅛ x 1 3/4 ) = 194 + 28 + 42 7/16 = 264 7/16 square inches.
Surface area if scaled up by a factor of 10: 10^2 = 100. 26,443 ¾ square inches.
Volume = 8 x 12 ⅛ x 1 ¾ = 169 ¾ cubic inches.
Volume scales down by 1/10
â…“^10 =3 â…“
â…“ = 100/3 divided by 3 = 3/100
Please give measurements for Length = Width = Height =
of the cereal box. Describe the cross section of the box
