Question

find volume, total surface area, lateral surface area and the length of the diagonal of cube each whose edges measure 80cm

Answer 1

Given :-

➪ Edge of the cube = 80cm

To find :-

➪ Volume

➪ Total surface area

➪ Lateral surface area

➪ Diagonal length

Formulas used :-

➪ Volume = a³ cm³

➪ Total surface area = 6a² cm²

➪ Lateral surface area = 4a² cm²

➪ Diagonal length = √3a cm

Solution :-

➪ Volume = 80 × 80 × 80 = 512000 cm³

➪ Total surface area = 6 × 80 × 80 = 38400 cm²

➪ Lateral surface area = 4 × 80 × 80 = 25600 cm²

➪ Diagonal length = √3a = 1.732 × 80 = 138.56 cm

Answer 2

Answer:

otal surface area = 6a² cm²

➪ Lateral surface area = 4a² cm²

➪ Diagonal length = √3a c
