We know that
[surface area]=2*[area of the base]+[perimeter of the base]*height of prism
area of the base= area of <span>a equilateral triangle
b=3 cm
h=2.6 cm
area of the base=b*h/2-----> 3*2.6/2----> 3.9 cm</span>²
perimeter of the base=perimeter of a equilateral triangle
b=3 cm
perimeter=3*(3)-----> 9 cm
[surface area]=2*[area of the base]+[perimeter of the base]*height of prism
[surface area]=2*[3.9]+[9]*6-----> 7.8+54-----> 61.8 cm²
the answer is
61.8 cm²
Answer:
8(n+4)
Step-by-step explanation:
Answer:
See Below
Step-by-step explanation:
To get volume of cuboid, we multiply the 3 dimensions.
<u>Volume of Box</u> = 28 * 15 * 20 = 8400
<u>Volume of 1 disc case</u> = 1.5 * 14.2 * 19 = 404.7
<u>Volume of 17 disc cases</u> = 17 * 404.7 = 6879.9
Since, volume of 17 disc cases is less than volume of the cuboid box, definitely 17 disc cases will fit the box.
