Answer:
488
you need to find surface are and the formula is : a=2(wl+hl+hw)
with the numbers plugged in the equation is: 2(9x16+4x16+4x9)
now to multiply:2(144+64+36)
now to apply distributive property: 2x144 + 2x64 + 2x36
288 + 128 + 72
416 + 72
488
The 488 square inches cardboard does Jessica need to make a rectangular prism with length of 16 inches, width of 9 inches, and height of 4 inches.
It is defined as the six-faced shape, a type of hexahedron in geometry.
It is a three-dimensional shape. It is also called a cuboid.
We have:
Rectangular prism with length of 16 inches, width of 9 inches, and height of 4 inches
The amount of cardboard needed to make a rectangular prism
= surface area of the box
Surface area of the box S = 2(lw + lh + wh)
= 2(16×9 + 9×4 + 4×16)
= 2(144+36+64)
= 488 square inches
Thus, the 488 square inches cardboard does Jessica need to make a rectangular prism with length of 16 inches, width of 9 inches, and height of 4 inches.
