side length of w = 45×w/1000t cm
the actual length of side t is .045 cm.
and we have to use the scale drawing to find the actual side with a length of w.
to get the scale we will use unitary method.
∵ length t is measured on scale=.045 cm
∴ length of w will be measured as (.045×w)/t cm
or length =
answer:s.a. = 486 in²
the formula of a volume of a cube:
a - length of edge
the formula of a surface area of a cube:
we have v = 729 ft³. substitute:
