Answer:
8.0 × 10⁴
Step-by-step explanation:
1.2 × 10⁵ - 4.0 × 10⁴
1.2 × 10⁵ = 120000
4.0 × 10⁴ = 40000
120000 - 40000 = 80,000
8.0000 (4 spaces)
8.0 × 10⁴

Answer:
52 cm^2
Step-by-step explanation:
To find the rectangular area on the bottom you multiply 3 by 5 = 15 cm^2.
To find the triangular area on the sides you multiply 4 by 3 = 12 cm^2 then divide by 2 = 6 cm^2, but since there are 2 of them you multiply by 2 again and end up with a surface area of 12 cm^2.
To find the square area on the top you multiply 5 by 5 = 25 cm^2.
So the total surface area is 25+15+12 = 52 cm^2.
<em>Note: cm^2 represents cm squared</em>
