To calculate the surface area of a box (rectangular prism), use the formula: Surface Area = 2(lw + lh + wh), where l is the length, w is the width, and h is the height. For a box measuring 20 cm by 10 cm by 15 cm, the surface area is: 2(2010 + 2015 + 10*15) = 2(200 + 300 + 150) = 2(650) = 1300 cm². Thus, the surface area of the box is 1300 cm².
No, you cannot wrap a 15cm by 10cm by 10cm box using a single sheet of A4 paper. An A4 sheet measures 21cm by 29.7cm, which is not large enough to cover the surface area of the box completely. The surface area of the box is 2(15cm × 10cm + 10cm × 10cm + 15cm × 10cm) = 2(150cm² + 100cm² + 150cm²) = 2(400cm²) = 800cm², while an A4 sheet provides a limited area of 623.7cm².

A cylinder with a surface area of 200cm2 and a height of 20cm has a volume of about 137.96cm3
The surface area of a cylinder where height is 80cm and radius is 15cm equals 8953.54cm2
The curved surface area of a cylinder with a height of 8cm and diameter of 10cm is 251.33cm2

To find the area of a triangle, you use the formula: Area = 1/2 * base * height. Plugging in the values, we get Area = 1/2 * 10cm * 15cm = 75 square cm. Therefore, the area of the triangle with a base of 10cm and a height of 15cm is 75 square cm.
Area = 20*10 = 200 square cm

first tell me the formula
A cylinder with a surface area of 200cm2 and a height of 20cm has a volume of about 137.96cm3
The surface area of a cylinder where height is 80cm and radius is 15cm equals 8953.54cm2
The surface area of a 15cm plate can be calculated using the formula for the surface area of a circle, which is A r2. Since the plate is circular, the radius (r) would be half of the diameter, which is 15cm. Therefore, the surface area would be A (7.5)2 176.71 square centimeters.
200 sq. cm.
area = length x width = 20 x 15 = 300 sq cm
The curved surface area of a cylinder with a height of 8cm and diameter of 10cm is 251.33cm2
