Question

3x + 9ly = 41
25x+10y = 89
x not belongs to y = ?​

Answer 1

Answer:

Step-by-step explanation:

Let the height = height

Then volume= l× b×h

= 192 cm ka cube = 8cm× 6cm× height

= height= 192 cm ka cube upon mein 8× 6cm ka square

= height = 192 cm ka cube upon mein 48 cm square

= height = 4 cm

Therefore , (i) height = 4 cm

(ii) surface area = 2 ( lb+ bh+ HL)

= 2 (8×6+6×4+4×8) cm ka square

= 2(48+24+32) cm ka square

= 208 cm ka square

(iii) lateral surface area= 2( l+b) h

= 2 (8+6)×4 cm ka square

= 2(14) × 4 cm ka square

= 28 ×4 cm ka square

= 112 cm ka square
