So there are a number of ways to solve this one. You could A: find the area of the desk in feet, and then convert feet squared to inches squared, or B: convert feet to inches First, and then multiply to find the area. I prefer method B, the math would be: 4 x 12 = 48. 3 x 12 = 36. 48 x 36 = 1728. Your final answer should be: 1728 in².
Answer:
644
Step-by-step explanation:
SA=[2×(5×20 + 5×6 + 20×6)] +
[2×(4×12 + 4×6 + 12×6)] -
[ 2× 12×6]
= [2×(250)]+[2×(144)] - [144]
= 500+288-144
= 644 cm²
