Answer 1

Answer:

According to the Question

When two cube with edges are joined end to end . It form new shape Cuboid. So the dimension in this case are

Length ,l = 6+6 = 12 cm

Breadth ,b = 6 cm (remain same)

Height, h = 6 cm (remain same)

So we have to calculate the surface area of Cuboid(S).

• Surface Area = 2(lb+bh+lh)

Substitute the value we get

:\implies:⟹ Surface Area = 2(12×6+6×6+12×6)

:\implies:⟹ Surface Area = 2(72 +36 +72)

:\implies:⟹ Surface Area = 2(180)

:\implies:⟹ Surface Area = 360 cm²

Hence, the surface area of the resulting cuboid is 360cm². Required Option is (b) 360cm².

Now, we have to calculate the slant height .

height ,h = 40 cm

radius ,R = 24 cm

radius ,r = 15 cm.

• Slant height, l² = h² + (R -r)²

Substitute the value we get

\longrightarrow⟶ l² = 40² + (24-15)²

\longrightarrow⟶ l² = 1600 + (9)²

\longrightarrow⟶ l² = 1600 + 81

\longrightarrow⟶ l² = 1681

\longrightarrow⟶ l = √1681

\longrightarrow⟶ l = 41

Hence , the slant height is 41 cm

Answer 2

Answer:

Photosynthesis is a process by which phototrophs convert light energy into chemical energy, which is later used to fuel cellular activities. The chemical energy is stored in the form of sugars, which are created from water and carbon dioxide.
