Tatiana wrote the steps that are commonly used to solve a system of equations with two variables. Which steps are correct? Check

all that apply. Multiply the value of the first variable by one of the original equations to solve for the second variable. Use multiplication to write an equivalent equation with an opposite term. Solve for one of the variables. Write the opposite of one variable to solve for the other variable. Add the equivalent system of equations to eliminate a variable. Write the solution as an ordered pair. Substitute the value of the known variable into one of the original equations to solve for the unknown variable.

1. A wooden box is to be built so that it measures 156 cm by 122 cm by 95 cm.
NeX [460]

The amount of plywood needed to build the garbage bin is the surface area. Therefore, the amount of plywood needed is 90884 cm².

<h3>How to find the surface area of a rectangular prism</h3>

The wooden box is a rectangular prism. The amount of plywood used to construct the wooden box is the surface area of the box.

Therefore,

surface area of rectangular prism = 2(lw + lh + hw)

where

  • l = length
  • w = width
  • h = height

l = 156 cm

w = 122 cm

h = 95 cm

surface area of rectangular prism = 2((156 × 122) + (156 × 95) + (122 × 95))

surface area of rectangular prism = 2(19032 + 14820 + 11590)

surface area of rectangular prism = 2(45442)

surface area of rectangular prism = 90884 cm²
