Answer:
No, she cannot completely cover the footrest.
Step-by-step explanation:
First of all, we need to find the total surface area of the prism to be covered using the cotton cloth
the total surface area of the prism is
A = 2wl + 2lh + 2hw,
l is the length of the prism = 18 in,
w= width of the prism = 12 in,
h is the height of the prism = 10 in
hence [tex]A = 2(12 \times 18 ) + 2(18 \times 10) + 2(10 \times 12)=1032in^{2}[/tex]
We need to convert the area of the fabric to be in the same unit as that of the prism
Area of cotton fabric = [tex]1 yd^{2}= 1296 in ^{2}[/tex]
since the surface area of the foot rest is more than the area of fabric she has, she cannot completely cover the footrest
