Question

1. Find the total surface area and lateral surface area of a cube whose each edge is:
a. 5 cm
b. 2 dm
C. 0.7 m​

Answer 1

Answer:

b.2 dm

Step-by-step explanation:

Total surface area of a cube = 6 (side)2. Lateral surface area of a cuboid = 2 × height × (length + breadth). Total surface area of a cuboid = 2(lb + bh + hl). Lateral (curved) surface area of a cylinder = 2πrh.

Answer 2

surface area = 6a^2

lateral surface area =4a^2

a

5cm

TSA = 6*5^2

= 25*6

=150cmsaq

LSA =4a^2

=25 *4

=100

0.7

lsa = 4a^2

=4 * 0.49

1.96

tsa =6a^2

6 *0.49

2.95
