Find the surface area of this rectangular prism.

Alexeev081 [22]

Answer:

Surface area of the rectangular prism= $168 yards^2$

Step-by-step explanation:

Given Dimensions of the rectangular prism are:

$Length(L)= 9 yards\\\\Width(w)=2 yards \\\\Height(H)= 6 yards$

Surface Area of a rectangular prism=

$2(L*W+W*H+H*L)\\\\ =2(9*2+2*6+6*9)\\\\ =2(18+12+54)\\\\ = 2(84)\\\\$

= $168 yards^2$

The surface area of the rectangular prism is $168 yards^2$

Solve the equation and check the solution.

myrzilka [38]

A - 2 1/2 = 1 1/2

Solve for A by adding 2 1/2 to both sides:

A = 1 1/2 + 2 1/2

A = 4

The answer is c. A = 4

Check: 4 - 2 1/2 = 1 1/2
