Answer:
D) L = 315 cm2 ; S = 399.9 cm2
Step-by-step explanation:
Lateral area;
3 × (½)(14)(15)
315 cm²
Surface area:
315 + (½)(14)(14)sin(60)
399.8704896 cm²
the answer is 60.
all you have to do is multiply all the numbers.
3 × 4 × 5 = 60
first:
multiply two of the numbers together. anything you like.
4 × 3 is 12
and now multiply the left number with the
result.
which is
5 × 12 = 60
The answer is 1.9 gallons
40 feet or 13 yards and 1 foot
using the conversion
1 yard = 3 feet then 1 yard 2 feet = 5 feet ← material for 1 pillow, hence
8 pillows require 8 × 5 = 40 feet
