Question

Object 1: Cereal Box

3D shape: Rectangular Prism
Dimensions:
length = 12 inches
width = 8 inches
height = 1.75 inches


Object 1 3D shape: Rectangular Prism (cereal box)
SA Formula:

Surface Area:

Answer 1

The surface area (SA) formula for a rectangular prism is:

SA = 2lw + 2lh + 2wh

where l is the length, w is the width, and h is the height.

For the cereal box object given, we have:

l = 12 inches

w = 8 inches

h = 1.75 inches

So, substituting these values into the formula, we get:

SA = 2(12)(8) + 2(12)(1.75) + 2(8)(1.75)

SA = 192 + 42 + 28

SA = 262 square inches

Therefore, the surface area of the rectangular prism cereal box is 262 square inches.

Explanation:

Answer 2

The SURFACE AREA OF THE RECTANGULAR PRISM is 262 in²

SURFACE AREA (S.A) OF RECTANGULAR PRISM= 2lw+2lh+2wh

LENGTH=12 inches

WIDTH= 8 inches

HEIGHT=1.75 inches



Applying the formula

We get

S.A=2*(12*8)+2*(12*1.75)+2*9(8*1.75)

S.A = 192+42+28 sq inches

S.A= 262 sq inches
