Question

Two cubes of volume 64cu. cm is placed next to each other, find the T. S. A. of the cuboid formed

Answer 1

side of each cube = 4units

length of cuboid=8units
height=4units
breadth=4units

TSA= 2(lb+bh+hl)
2 (32+16+32)
160sq.units

is the TSA of cuboid

Answer 2

Question:

Two cubes of volume 64 cm³ each is placed next to each other. Find the Total Surface Area of the cuboid formed.

Solution:

Find the length of each cube:

Volume = length³

length³ = 64

length = ∛64

length = 4 cm

Find the area of 1 face:

Area = Length x Length

Area = 4 x 4 = 16 cm²

Find the total surface area:

Total Surface area = 10 faces

1 face = 16 cm²

10 faces = 16 x 10 = 160 cm²

Answer: The total surface area is 160 cm²
