185ft squared
Step-by-step explanation:
since this is a composite solid, all we have to do is use the 2 formulas:
b x h / 2 (Triangles on the pyramid)
l x w (Rectangular faces)
to solve the surface area of the composite figure.
160% of 19 is 30.4
Convert 160 into a decimal: 160%/100 = 1.6
Multiply the decimal by 19: 1.6 × 19 = 30.4 <-- our answer.
