Write a polynomial function in standard form with zeros at –3, 5, and 1

9,270,000 sq m

Step-by-step explanation:

From the question,

Length = 24cm

Width = 21cm

Height = 30cm

Scale used = 1cm : 50m

Actual Length = 24 × 50 = 1200m

Width = 21 × 50 = 1050m

Height = 30 × 50 = 1500m

The surface area will then be calculated as:

= 2(1200 x 1050) + 2( 1050 x 1500) + 2(1500 x 1200)

= 2(1260000) + 2(1575000) + 2(1800000)

= 2,520,000 + 3,150,000 + 3,600,000

= 9,270,000 sq m
