1. SA = 148m^2

Solution:

A: Understand

Asked:

  • What is the surface area of the given rectangular prism.

Given:

  • L = 6m
  • W = 5m
  • H = 4m

B. Plan

Operation:

  • Multiplication and Addition

Equation:

  • SA = 2(W × L)+ 2(W × H)+ 2(H × L)

C. Solve

Solution:

  • SA = 2(5 × 6)+ 2(5 × 4)+ 2(4 × 6)
  • SA = 148m^2

Answer:

  • Therefore the surface area of the given rectangular prism is 148m^2

2. SA = 7,539.82cm²

Solution:

A. Understand

Asked:

  • What is the surface area of the given cone problem.

Given:

  • B = 40cm
  • SH (slant height) = 20cm

B. Plan

Operation:

  • Multiplication and Addition

Equation:

  • SA = πr² + πrl

C. Solve

Solution:

  • SA = πr² + πrl
  • SA = π (40)² + (40) (20)
  • SA = 1,600π + 800π
  • SA = 7,539.82cm²
